The 12 days of Solstice - Day 12 - sunlight in the passage of Newgrange on the dawn of Winter Solstice

Winter Solstice has officially arrived. Today the sun reaches its minimum declination - its furthest southerly position in the sky. This is the turning point of the year. As the sun rises above Red Mountain in the Boyne Valley this morning (weather permitting), its light will enter through an opening above the passage entrance known as the 'roof box' and will illuminate the central chamber, which lies about 20 metres inside the cairn, for around 17 minutes.  The lucky Winter Solstice Lottery winners will be inside, while hundreds will gather outside. This year, there will be 20 Irish wolfhound dogs at Newgrange too. It should be a great morning.

The photo shows a view taken on Winter Solstice 2010 just as I was emerging from the chamber where I had witnessed the solstice illumination for the first time. As you can see, there are two beams of light. The main area of light, on the floor and the lower part of the passage orthostats, enters through the main doorway. This might have been closed by a large slab during winter solstice ceremonies in ancient times. The upper beam is a much shallower beam, and is visible higher up on the orthostats in the left of the image. This is the light that comes in through the roof box, and it is only this beam that reaches the floor of the chamber within.

As we reflect upon the coming of the glorious light of dawn into the dark void, and the turning of the year, we hope that events in the wider world which have led humanity into darkness in recent times will turn also, and that the hearts of those who have resorted to anger, hatred or fear are softened, so that we can better learn to get along with each other. For that is one of the central themes of the ancient myths involving the Tuatha Dé Danann, the gods who were said to have owned and built Newgrange. When the Milesians came from Spain, to take Ireland by force, there was initially some fighting and, after losses on both sides, the Dé Dananns and the Milesians reached an accord. The Dé Dananns would occupy the sídhe, these great palaces of stone and earth that allowed access to and from the otherworlds, while the Milesians would occupy the surface of the land. And so it is that we must learn to get along with our fellow humans. We must learn to get along together. What is the alternative, except suffering and misery?

Today, as the sun shines into the heart-shaped mound of Newgrange, and warms its interior with a golden light, we ask that a light shines into the hearts of all our fellow human beings, that we might learn to reach an accord that looks to the ending of hate and discrimination, and allows for a peaceful settlement of all conflict. That is the most urgent message from Newgrange for today's world.

The 12 days of Solstice - Day 11 - Winter Solstice sunrise viewed from the doorway of Newgrange

It's day 11 of my new series of photographs entitled 'The 12 days of Solstice'. This is the second-last image in the series. It shows the sun not long after it has risen on the shortest days of the year at Winter Solstice. The picture was taken just inside the entrance of the passage of Newgrange. Above my head in this image is the specially constructed aperture known as the 'roof box'. This is the portal which allows sunlight to penetrate the entire length of the passage and into the chamber. The light that enters through the actual doorway does not reach the chamber floor. The two beams of light are kept separate by the stone seen in the top of this image.

Immediately in front of the entrance is the large kerb stone, K1, which on its front side (the side facing the sun) has the famous tri-spiral design among other lavish engravings. At the time this photo was taken, the sun's light had already left the chamber again. It shines in there for 17 brief minutes. There is something very special about the quality of the light immediately at sunrise. As soon as the sun rises above the ridge known as Red Mountain (Roughgrange), its golden light reaches into the corridor of Newgrange and shines a narrow beam of light onto the darkened floor of its central chamber. It is at this moment that the year is seen to have reached its turning point. The old year dies and the new year is born. Dagda, the father god, yields ownership of Síd in Broga (Newgrange) to his son, Oengus Óg, the youthful sun.

From this moment, following a period of about a week when the sun's rising position has stood still on the horizon, it begins its slow movement back towards the east, and after a few weeks the light will get stronger and the days longer.

The 12 days of Solstice - Day 10 - the famous triple spiral on stone C10 in the end recess of Newgrange's chamber

This carved design, on the side wall of the end recess in Newgrange's chamber, is one of the most readily identifiable symbols from the ancient megalithic world. It is a design that is unique to Newgrange. It is not found anywhere else. It's often referred to as a triple spiral, but this is not an entirely accurate description of it, as Clare O'Kelly pointed out in her description of this stone:

C10, the three-spiral stone (often wrongly called a triple spiral: since a double spiral, like those on the entrance stone, consists of two parallel coils, by analogy a triple spiral should consist of three; in fact, the design consists of three double spirals, the two on the right being S- or returning spirals as well). In order to integrate the left-hand spiral into the design the two free ends of its outermost double coil were separated so as to sweep concentrically around the two other spirals and to meet again having encircled the S-spirals. The whole pattern is only 30 x 28 cm. The spirals are beautifully picked in broad shallow channels so that the intervening bands stand in relief. The design is executed on the undressed surface, but an area of pick-dressing on the left partly encroaches it.(1)

One thing the archaeologists tend not to do (although that is not an exclusive tendency) is to try to interpret the meaning of the symbols. There are many, many theories as to the meaning of the triple spiral (should that be the triple double spiral?) Its position within the end recess, but on a side wall, means that, contrary to some speculation on the internet, the winter solstice sun beam does not strike it directly. Rather, it is illuminated by reflected light. So what does it mean? Does it mean anything?

My own speculation has revolved around the mythology and the astronomy of the monument. In myth, there are two significant "trinities", or trios of figureheads. Tochmarc Étaíne (the Wooing of Étaín) is believed to have been written in the eighth or ninth century AD, but the true genesis of its story cannot be known. It describes how Dagda, the chief of the god, the Tuatha Dé Danann, desires Bóinn (the goddess after whom the River Boyne is named). He sends Bóinn's husband Elcmar away and lies with Bóinn and they conceive a son, Oengus Óg. So we have father god, mother goddess, and divine offspring. The second trinity consists of Lugh, Dechtine and Sétanta. Dechtine comes to Newgrange in wintertime from Emain Macha (Armagh) and while there Lugh (another of the chief gods) appears to her in a dream and tells her she will bear a son, and that he will be called Sétanta. Sétanta later becomes Cúchulainn. Perhaps the triplicate of spirals represents the trinity of gods?

Separately, we find that several heavenly objects cast their light into Newgrange. One of these, as we know, is the sun. Each year on Winter Solstice, the light of the rising sun enters the long corridor of Newgrange and shines into its inner chamber. What is much less well known is that sometimes the full moons in summertime shine into Newgrange. Further to this is the fact that Venus, as the Morning Star, is said to cast a beam into the chamber of Newgrange once in eight years.

The 12 days of Solstice - Day 9 - red sky over Newgrange

It's day 9 of my series 'The 12 days of Solstice' and today's image features a red sky over Newgrange. One of the benefits of living relatively close to Newgrange is that I get to be there regularly. This means I have seen and photographed Newgrange under many different skies. The weather in Ireland is so changeable that every sunrise is different and every sunset too. And sometimes even after the sun has set, something like the above happens. As usual with red skies, this one didn't last long - no more than five minutes - but at its peak it was beautiful.

The 12 days of Solstice - Day 8 - megalithic art on kerb stone 52, one of three highly decorated kerbs

This is kerb stone 52 at Newgrange, which lies at the rear of the mound, exactly opposite the main entrance kerb stone. It is one of just three highly decorated kerb stones at Newgrange. The others are kerb 1, the kerb immediately in front of the entrance to the passage, and kerb stone 67, on the northeastern side of the kerb.

As you can imagine, interpretation of the symbols carved into stone at Newgrange and its sister monuments over 5,000 years ago is necessarily subjective, and there is a wide range of theories as to what various emblems and designs on different stones mean. My own view is that there's no great harm engaging in speculation - however, one has to be careful about ensuring that the archaeological evidence is not disputed by your theory. For instance, one gentleman I encountered some years ago insisted that symbols on a passage stone at Cairn T, Loughcrew, were figures including the biblical partriarch Jeremiah, sailing on a boat to Ireland. This same individual insisted that Newgrange is an Iron Age construction, and all the archaeologists are wrong about its date!

My own theory (and because it's just a theory, I could be wholly wrong about it) is that it might contain symbols representing Orion and Sirius. At the time Newgrange was built, around 3150BC, the declination of Sirius was -23º 2' 43.1". This means that its rising position would make it visible from the chamber of Newgrange, out through the roofbox. A prostrate observer on the floor of the chamber could have seen this "dog star" (or whatever it might have been called back then) night after night at certain times of the year. However, due to the effects of precession of the equinoxes, a slow wobble of the earth's axis, Sirius's declination was increasing, and over the next couple of centuries it would have drifted northwards, so that it was no longer visible from the chamber.

Some of the engravings on kerb 52 could be interpreted as representations of Orion's belt and Sirius:

On the right-hand side of the stone, there are three sets of three circular holes, known in archaeological terminology as "cup marks". Each of these sets of holes is contained within a double oval-shaped cartouche. There are a number of other cup marks on the stone, the most noticeable of which is one contained inside the vertical stripe in the centre of the stone. Is this Sirius, sitting on the axis of the site, which runs through the entrance kerbstone, K1, up the passage, and out the other side of the kerb in the centre of K52?(1)

Maybe it is, maybe it's not. This is the nature of speculation. But at the very least this theory fits the astronomical evidence and does not dispute the archaeological evidence - always a good starting point!

The presence of the vertical line or stripe on this stone led archaeologists to speculate that there might be another passage behind it. Prof. Michael O'Kelly excavated an area of the mound behind this stone in search of just such a passage, but no evidence of one was found.

The 12 days of Solstice - Day 7 - the eastern recess of Newgrange, the holy of holies, and its giant basins

It's day seven of 'The 12 days of Solstice' and today's image features the eastern (right-hand) recess in the chamber of Newgrange. This is clearly a very sanctified space, a "holy of holies", so to speak. It is the largest of the three recesses and has features that endow it with a particular sense of preeminence, a place almost beyond encroachment by human thought or deed.

The recess features a highly decorated ceiling stone, something not shared by the other recesses (admittedly the end recess has the famous tri-spiral carved into a stone forming its side wall). It effectively has two basin stones - one sitting upon the other. The smaller of the two features two hollow depressions towards its rim, the purpose of which is not entirely clear. The larger "basin" is in fact an enormous slab whose top surface has been hollowed somewhat. It is clear that this giant slab must have been in position BEFORE all of the surrounding orthostats were put in place. It is certainly not the sort of thing that could have been dragged up the passage and hauled into place in the chamber after these structures had been completed. All of this begs a question - was this giant stone the first piece of Newgrange to be put in place when construction began? By necessity, it must have been one of the earliest phases of the construction of the monument we know today as Newgrange.

What took place in this sanctified space? Were these basins used for the placement of the fragmented remains of the dead? Over 2,000 bone fragments were found at Newgrange. Many were so small as to be unrecognisable. We are told at least five individuals were represented in the remains. But it could be a lot more. Clearly, there were methods of defleshing/excarnation, cremation, and perhaps there were even processed involving the pulverization of the remains of the dead. Were the bone fragments also washed before deposition in the sacred spaces within Newgrange and its sister sites?

The eastern recess might be dry today, but that certainly was not always the case:

Time and time again, from the rediscovery of the chamber in 1699 up until O'Kelly's installation of a protective concrete umbrella over the vault, water had been found to be dripping or trickling into the monumental slab and bowl in the righthand recess.(1)

This presence of water, despite the laborious efforts of the builders to redirect the flow of water across the capping stones of the passage, etc, led one author to suggest that the presence of water in this recess might have been intentional. Jacqueline Ingalls Garnett has speculated that the intention might not have been to deposit bones in the basins, but rather to bring them in there for some special ceremony involving this "holy water".

It is possible that the object was exactly to bring the packet of remains into contact with the solemn, numinous font whose water - perhaps mixed with dew - trickled from the heavens into the righthand-recess bowl. In fact, unless the entire monument had been built in order that one or two sets of bones could be laid in the bowl, the idea may well have been that it was somehow beneficial for the deceased that his bones should have an opportunity however brief to contact the water in the bowl perhaps by dipping or sprinkling.

It's an interesting idea, but one wonders to what extent the huge crack in the ceiling stone (which is obviously not an original feature!) contributed to this water ingress. Furthermore, we might ask if there are other monuments of similar age and design where this is seen to happen and is considered intentional.

Garnett points out something else that is interesting - the fact that a natural spring was present in the passage, a "winter-flowing stream" that emanated from under passage orthostat R8. This spring was culverted during excavation and reconstruction work, but might have been a crucial element of the sacred infrastructure of the site when it was built.

Whatever took place in terms of ritual or ceremonial activity in the eastern recess in prehistory, it remains a space that demands reverence. It's not a room or space that invites one to come in and stand around. It is very much a space that stands alone.

Time lapse video - winter evening setting sun illuminates southern chamber at Dowth megalithic monument

It was shaping up to be a lovely time lapse video. I wanted to record the setting sun shining into the southern chamber of Dowth. It's six days until Winter Solstice, and the sky was nice and clear, so I headed out to Dowth with the cameras hoping to catch the illumination of the chamber. As you can see, all was going well, but an encroaching Atlantic front - bringing rain - started to shroud the sun just at the crucial time, and cut off the light, which had begun to reach the chamber floor.

I guess I will just have to try again, if and when the opportunity arises.

Make sure to watch the video full screen and in 1080 high definition. (To do that, press play on the video, and when it starts playing click on the YouTube logo on bottom right. That will open the video in a new window. Then click the full screen and HD settings either side of the YouTube logo).

The 12 days of Solstice - Day 6 - Venus, the Evening Star, in the winter twilight sky over Newgrange

It's Day 6 or 'The 12 days of Solstice' and today's image features Venus, the Evening Star, over Newgrange at dusk in winter. The cycles of the heavenly bodies were undoubtedly recognised by early societies across the world. At Newgrange, the yearly cycle of the sun is definitively memorialised through the alignment of its passage and chamber with Winter Solstice sunrise. Less well known is the fact that at certain times of the year the moon can also cast its light in through the roof box and into the passage and sometimes the chamber.

The bright planet Venus, which is the third brightest object in the sky after the sun and moon, follows a distinct pattern over the course of eight years, sometimes appearing in the mornings before sunrise for a number of weeks or months, and sometimes appearing in the evening after sunset. After eight years, this pattern repeats. Could the builders have seen and known this?

Joseph Campbell wrote about a folk belief in the Boyne Valley that suggested the morning star cast a beam of light into the chamber of Newgrange once every eight years, at dawn. Uriel's Machine authors Christopher Knight and Robert Lomas suggest that a series of eight markings on the lintel stone above the roofbox of Newgrange represent the eight years of the Venus cycle. Indeed, on one year out of every eight, Venus rises on the morning of the Winter Solstice around an hour before the sun and an observer prostrate in the chamber of Newgrange would be able to see it through the roofbox.

In her guise as the morning star, Venus was known in Ireland as caillichín na mochóirighe, the 'early-rising little hag'.(1)

As you can see from the image above, Venus is a brilliant object. Compare it with the several stars visible in the image, which are much fainter. It is said that in complete darkness, away from city lights, the light of Venus casts a shadow. The folklore recorded by Campbell suggests that, once every eight years, the Morning Star "may be seen to rise and cast its beam precisely to the place of the stone with the two worn sockets".(2)

The 12 days of Solstice - Day 5 - ribbed stone at the threshold of the chamber of Newgrange

It's day 5 of 'The 12 days of Solstice' and today's image is a photo of passage stone R21, which lies at the threshold between the passage and the chamber of Newgrange. The grooves and ridges which have been formed on this stone by picking remind one perhaps of ribs. On the morning of winter solstice, the sunbeam strikes the bottom of this stone before passing into the chamber.

This highly unusual ribbed stone is not entirely unique. Another passage stone, R12, features three similar grooves. Their meaning is not known. I cannot help thinking of a rib cage, and in particular an obscure myth from the Boyne Valley which may be one of Ireland's original creation myths. It is the story of the Mata, a giant monster that was ripped into pieces and thrown chunk by chunk into the Boyne River. The monster was killed at Brug na Bóinne. The myth seems typical of that cluster of myths around the globe which sees creation preceded by an act of dismemberment, something which leads creation myth author Philip Freund to entitle his chapter about it 'Out of the monster'. In all of these myths, he says, "the cosmos is carved out of some slain monster's body'(1).

In the case of the Mata, its remnants form natural features of the landscape. Note in this passage how it is distinctly stated that the monster was slain on a stone "in" the Brug of Mac Oc (Newgrange):

When the men of Erin broke the limbs of the Matae, the monster that was slain on the Liacc Benn in the Brug of Mac Oc, they threw it limb by limb into the Boyne, and its shinbone (colphta) got to Inber Colptha ("the estuary of the Boyne"), whence "Inber Colptha" is said, and the hurdle (clíath) of its frame (i.e. its breast) went along the sea following the coast of Ireland until it reached yon ford (áth); whence "Ath Cliath" is said.(2)

Mata, which is an Irish word meaning "great, dark, gloomy", was destroyed at Newgrange. He was thrown, in pieces, into the Boyne, where his ribcage (clíab/chléib = of the framework of the ribs) made its way down along the coast and formed the ford of the River Liffey in Dublin.

Another curiosity is the fact that, viewed from the passageway looking towards the chamber, this ribbed stone has the shape of a salmon. The Salmon of Knowledge is an important story connected to the Boyne - to Fiacc's Pool, which is only a short distance upriver, between Rosnaree and Knowth.

The 12 days of Solstice - Day 4 - the doorway of Síd in Broga (Newgrange) lit up in the beautiful winter twilight

It's day 4 of my series of photos called 'The 12 days of Solstice'. Today's image shows Newgrange at twilight, with its portal aglow, as if a fire was ablaze in its doorway. One can almost imagine the Daoine Sídhe (The good people, fairies) dancing and singing there in the winter twilight.

The 12 days of Solstice - Day 3 - megalithic art on Newgrange passage stone L19 ... guardian stone?

It's day 3 of my series of photographs called 'The 12 days of Solstice' and today's image features a passage orthostat from Newgrange known as L19 and its beautiful megalithic art. The archaeologist, Michael O'Kelly, numbered the kerb stones, the passage stones and chamber stones. The left-hand passage stones were given an 'L' designation, the right-hand ones an 'R' and the chamber stones 'C'. L19 stands out as the most heavily decorated of the passage orthostats.

Many of these passage uprights have little or no decoration. Some are pick-dressed, a technique which basically removes the outer "skin" of the stone. L19 is heavily pick-dressed above and below the zig-zags and spirals seen in this photo. In fact, some of this pick-dressing has obliterated some spirals on the lower part of the stone. We're not at all sure why this was done.

What we do know is that L19, because of this vividly carved decoration,  is one of the stand-out stones of the narrow corridor leading towards the chamber of Newgrange. The arrangement of the three spirals, with a lozenge in the middle, has led to some people referring to the design as a face, perhaps of some deity or spirit. In this respect, it might be seen as a guardian stone.

The 12 days of Solstice - Day 2 - the golden glow of a beautiful winter sunset at Newgrange

Today is the second day of my new series of Newgrange photographs entitled 'The 12 days of Solstice". Today's image shows Newgrange in winter at around sunset. The sun has just disappeared below the near horizon, but its golden glow is still very much visible. The winter days are short in the Boyne Valley - in midwinter, the sun rises shortly before 9am and sets before 4pm. This dearth of light and heat reminds us how difficult life might have been around solstice in the Neolithic, and how important the turning of the year was to the builders of these huge monuments.

As a photographer, I enjoy the special light that happens at sunrise and sunset in winter. Even when it's cold, and maybe your hands are numb from holding the camera, the golden glow of the sun helps to warm the soul. Sunrise and sunset are very special times, and provide the observer with a moment of exhilaration and gladness. One can only imagine that the builders of Newgrange experienced  similar moments of bliss punctuating their lives as they grappled with some meaning behind their own existence.

Celebrating winter solstice season with a new series of images of Newgrange called 'The 12 Days of Solstice'

The first image from my new series called 'The 12 days of Solstice' shows the corbelled ceiling of the chamber
of Newgrange. This photo was taken with a wide-angle lens while lying on the floor of the chamber. The ceiling
was not disturbed during excavations and is undisturbed. The passage is at bottom, with the recesses partly
visible on left, top and right.

Today begins a 12-day countdown to the Winter Solstice, the shortest day of the year, which is celebrated every year at the 5,200-year-old Newgrange monument in the Boyne Valley. This year, as a special celebration of the solstice season, I am unveiling a set of images - one per day until solstice - based upon the idea of the song '12 Days of Christmas'.

Because the date of Christmas was undoubtedly chosen to coincide with the ancient pre-Christian celebration of the shortest days, I thought it would be a nice idea to do something based loosely around the twelve days of Christmas. However, instead of beginning on the special day, the series of images will be finishing on that day - the Winter Solstice - with the 12th image.

The series of images I have chosen is made almost exclusively of pictures that have never been seen before - with the exception of one. They show various images of Newgrange - interior and exterior - which I hope will evoke a mood of reverence for the ancestors, and perhaps an inclination towards reflection and contemplation about the deeper meanings of Newgrange, and how these might  permeate into our own lives.

For me personally, Newgrange is an extremely sacred and potent place. The idea - propagated in the abundant folklore and mythology of the sacred monument - that it is a liminal place, or point of access to other realms, is something that brings a deeper meaning to what it should represent for us, as individuals, and collectively as a society.

Newgrange functions as a mandala of sorts. It represents a prehistoric society's vista into an all-encompassing cosmology. It represents, symbolically, the earth, but an earth that is connected intimately with the wider cosmos. That connection is dramatically played out on the shortest mornings of the year, when a blade of golden light illuminates the dark cave in an awesome display that provides, for the modern observer, a moment of profound rapture. But it represents, more than anything, an image of hope - hope on two levels. The first is the hope that we can see the light after darkness, in a physical sense and also a psychological and spiritual sense. The other is that there is something beyond this life, something out there, through the "magic window", along the pathway of light, in another realm of existence.

There is much about Newgrange that is mysterious. But, when you've been there often enough, there is much that is hidden in plain sight. The antiquarians who visited the Boyne Valley monuments were, in some cases, undoubtedly looking for treasure - artefacts - things that would perhaps give them wealth and fame. However, the real treasure of Newgrange is far greater than any trinket of gold or venerated object of stone.

The real treasure of Newgrange is that it can serve as a mandala for us. It connects us with ancestors, those to whom we owe our very existence, and whose struggles through the dark periods of life were not in vain. It allows us a symbolic representation of something that is beyond the humdrum of ordinary life - opening a portal for us, perhaps, allowing ingression into sacred and divine realms. Newgrange - because it has endured and is still accessible to this day - offers an opportunity to experience a rapture and an awe, a pure exhilaration at the miracles of our existence, and indeed a space in which to contemplate the deepest of life's mysteries, those which were undoubtedly pondered by the ancestors of the Neolithic.

Where have we come from?
Who are we? 
Why are we here?
What happens to us when we die?

I hope you enjoy this series of images. I am very blessed to have been able to access Newgrange on many levels over the past two decades. I am, in particular, extremely grateful for the permission from the OPW that I have had to photograph its interior on many occasions over the years. I am especially thankful for having been able to witness the solstice illumination of the chamber, back in 2010. It is a very special place. I hope these photographs give you some sense of just how special it is.

Time lapse footage shows dramatic eclipsing of Dowth's solar eclipse symbols on Stone of the Seven Suns

The above video is a time lapse sequence showing the Stone of the Seven Suns (kerb stone 51) as it is lit up dramatically after sunrise in early December, with just two weeks to go to the Winter Solstice. The video features almost half an hour of footage compressed into one minute and 30 seconds. The symbols on the stone are thought to represent the sun, or perhaps even the sun during a solar eclipse, with ties in with the mythology about Dowth which suggests that its construction was abandoned when a sudden darkness fell over the land.

The time lapse footage reveals something fascinating. At first, the solar symbols are lit up quite dramatically, so that they are shown in excellent relief. Then, as the sun rises moves towards the south, a shadow from another kerb stone falls over the sun symbols - eclipsing the symbols one by one. If you can, make sure to watch the YouTube video at 1080 HD and full screen.

Kerb 49 (arrowed) is the one that casts
the shadow on kerb 51. Also shown here
is kerb 50, with its vertical line.

Unfortunately there was cloud blocking the sun early on, so the first of the seven sun symbols, which is on the far left of the stone, is already in shadow when the sun comes out. However, that does not spoil the show. Sit back and watch this marvel of megalithic magic! One can only speculate as to whether this "light and shadow" show was intentional on the part of the builders. The shadow from kerb stone 49, which is two stones to the left of the Seven Suns stone, causes the eclipsing of the symbols on kerb 51. However, it can be seen that kerb 49 leans forward somewhat (K49 is arrowed in the picture on right), and one has to be mindful about the possibility that this lean has happened in more recent times and was not, perhaps, part of the original design.

However, this interaction of light and symbols reminds me somewhat of the illumination of symbols that are not dissimilar to Dowth's seven suns on the back stone of Cairn T at Loughcrew. These symbols are lit up by sunrise on the spring and autumn equinoxes.

The interplay of light and shadow is also suggested at Newgrange, where shadows from the Great Circle stones appear to point towards, or "touch", kerb stones at the front of Newgrange at certain important times of the year, as described by Frank Prendergast.

Although I've been to Dowth several mornings lately to watch how beautifully the sun symbols are illuminated, I hadn't realised the extent of the phenomenon, or the slow progression of the shadow, until I saw the time lapse video. The video was made by taking a photography every two seconds. Because it compresses time, it shows the effect much more vividly.

The sun symbols lit up by the low winter sun. The shadow has not yet eclipsed these emblems.

The shadow crosses the stone diagonally, and interestingly the last sun to remain illuminated is the one which is currently at ground level. I presume the original Neolithic ground level is several inches below the current ground level and that the lower part of this symbol is hidden from view.

At around 9.15am, as shown in the above photo, the shadow from K49 is crossing the diagonal line on K50. Within about 15 minutes this shadow will have completely crossed K50 and will begin its slow progression across K51, eclipsing the eclipse emblems as it does.

The shadow from K49 is almost half-way across K51, the Seven Suns stone.

There is undoubtedly more to be learned about Dowth. It continues to provide surprises. Even though its mythology suggests a summer solstice influence, we can see the midwinter sunrise also has a dramatic "wakening" effect upon the few eastern kerb stones that are revealed. This is by far the best time of the year to view the Stone of the Seven Suns. At most other times, the megalithic art appears to be very flat and is sometimes difficult to see.

We shouldn't forget either that Dowth's southern passage and chamber are aligned so that the light of the setting sun on winter solstice shines inside, as shown in these beautiful photos by Anne Marie Moroney.

Winter sunlight does some beautiful things with the ancient megalithic art on the stones at Dowth

I've been able to spend a few mornings at Dowth recently. It's one of three of the great monuments of Brú na Bóinne (the others being Newgrange and Knowth), but is the least visited of the trio. Personally, I'm glad that Dowth retains this almost-forgotten status. It is not on the official tour. It is wild and overgrown, and many of its secrets are in the deep slumber of many centuries. I like it that way. It's a lovely place to spend time. Despite the fact that it is named after darkness (Irish Dubhadh), it presents a very interesting notion - the belief that we must experience the darkness of the longest night before the new year dawns.

While it near neighbour Newgrange is famous for its winter solstice sunrise alignment, Dowth's alignment to the sunset on the shortest day is less well known. Discovered (rediscovered) in 1980 by Martin Brennan and Jack Roberts, it was studied in detail over the course of a number of winters by Anne Marie Moroney, who published a lovely little book about it called Dowth: Winter Sunsets.

While the focus at Dowth is undoubtedly centered around winter sunset, there is something really beautiful that happens just after the sunrise on these short days of midwinter. The very well-known kerb stone 51 at Dowth, more famously referred to as the Stone of the Seven Suns (named so by Martin Brennan), is gloriously lit up by the warm luster of the midwinter sun. For about an hour after sunrise, these ancient solar symbols are highlighted in a dramatic fashion by the acute angle of the low sun. As a photographer who has spent many years photographing this stone under various lighting conditions, I can safely say that I have never seen them so impressively and dramatically in relief. It's quite striking. Below are a couple of photos showing some of the megalithic carvings, which are thought to be up to 5,500 years old, lit up by the winter sun.

The Stone of the Seven Suns is on the eastern side of the great mound of Dowth. Curiously, over on the southwestern side, the entrance stone to the southern chamber is also lit up by the morning sun in winter time. This is due to the alignment of the stone, which is orientated roughly northwest-southeast. There are two large cup holes on the stone, referred to by some as 'Lucy's Eyes'. There is also some worn megalithic art, which appears to be part of a spiral. A good bit of the stone is still buried beneath the ground - only the top third or quarter is visible above the surface.

The spiral and cup marks on the entrance kerb. I added flash to this one because the sunlight was a bit watery.

For a place that is named after darkness, the sun plays a big role at Dowth. It penetrates the southern chamber at midwinter, as we know. Until recent centuries, it probably also shone into the northern chamber around the time of Samhain and Imbolc sunsets (November/February). And there may be undiscovered passageways within its huge bulk. But as I said before, some of its secrets are in slumber. For now at least. And that's just the way I like it.
