Boyle’s Bealtaine: Rock Art, Ancient Festivals, and Archaeoastronomy

Bealtaine is one of the great ancient festival days, the one that heralds the beginning of the season of fertility in crops and animals. It marks the mid-point between the spring equinox and the summer solstice, making it a cross-quarter day, and this year it fell on May the 5th. For the non-Irish speakers out there, it’s not pronounced bell-tane, but byowl (to rhyme with owl, the bird) – tinnuh – Byowltinnuh. If you’re really keen on getting it right, you can listen to it here.

Things did not look promising as we arrived at the Giant’s Grave – cloud and fog

We devoted two posts recently to the subject of Boyle Somerville. The first was a post about his life and his pioneering work on what is now called archaeoastronomy, but which he called the new science of Orientation. The second was about a site that was close to his home in Castletownshend, Knockdrum Fort. In Boyle’s own article on Knockdrum (available online with a JStor subscription), he notes a particular orientation between two fallen galláns (or standing stones) on a slight prominence in the grounds of Drishane House, to Knockdrum Fort itself at sunset on Bealtaine in 1930.

Standing behind the Giant’s Grave, Knockdrum Fort is clearly visible on the horizon

On that day, he states, he stood on the fallen galláns and watched the sun set directly over Knockdrum Fort. Yesterday, we did the same thing. It was a nerve-wracking business as not only cloud cover but a constant drifting fog obscured the hills and we were not hopeful that we would be able to see anything at all. But Boyle was up there, looking down on us, and at the last minute the clouds parted and there was the sun, exactly where he said it would be, angling slowly down to the fort.

The sun lights up the Giant’s Grave, making the cupmarks on its surface more visible

Watching this descent was a real highlight of my life here in West Cork. First of all, it felt really special to be on the same spot as Boyle Somerville, 88 years later to the day, and verifying his sighting by recording the phenomenon with photographs and video. If anyone else has done it in the intervening years, we can find no record of it, but would love to hear about it.

Secondly, this is essentially a rock art story, rather than a stone fort story. As Boyle himself pointed out, the stone fort at Knockdrum is but one piece of evidence of a long and continuous use of this commanding site. There are two carved stones at Knockdrum, one outside the fort with cup-and-ring type carvings, and a cup-marked stone currently lying within it. Look back at Robert’s post to see photographs and drawings of these two stones. These examples of rock art are likely the oldest artefacts on the site, dating to between four and five thousand years ago. There is also a cross-inscribed slab, possibly indicating an Early Medieval use of the site for ecclesiastical purposes. The stone fort itself may have been a relatively recent period of occupation, marking it as the fortified residence of a high-status individual about a thousand years ago. Boyle felt it may even have been used for look-out and defensive purposes in the seventeenth century.

But the fallen galláns, known locally as the Giant’s Grave, also have cupmarks, tying them to the rock art tradition. The upper surface of the top slab has 17 cupmarks. Boyle counted 19 and the National Monuments record has it as 12, showing how difficult it can be to accurately identify man-made marks on a rough and heavily-lichened surface.

The Giant’s Grave, or fallen galláns, from the west side

While Boyle described this monument as two fallen galláns, it is unclear whether the placement of the two stones, one on top of the other, is accidental or deliberate. If deliberate, then this may be another type of megalithic structure, perhaps similar to a boulder burial (or clochtogle, as he preferred to call them). The orientation, then, as observed by Boyle in 1930 and by us in 2018, is from this probably Late Neolithic or Bronze Age structure to the place where other other pieces of rock art originally stood. Intervisibility, or the visibility of one piece of rock art from another, is well established in the Irish rock art literature. While we have written before (see here and here) about orientation from a piece of rock art to horizon markers, we have never before recorded a specific orientation, involving a solar event on a calendrical day, between rock art sites. So, this is a first for us, and may be a first for Ireland.

This is the Gortbrack stone, on its stand in the Stone Corridor at University College, Cork (UCC). It came from the townland next to Knockdrum Fort

In fact, it is easy to forget that three other examples of rock art come from adjoining townlands because they are no longer in situ: one is in the grounds of Drishane House and two are in Cork City. Six pieces of rock art less than 3 kilometres apart make for a ‘concentration.’

Above, the rock art currently in the grounds of Drishane House, but originally from Farrandeligeen

The Drishane House stone came from Farrandeligeen, immediately west of Drishane townland. In the field notes kept by Boyle, and discovered by Dr Elizabeth Shee, he notes that the stone was originally built into the wall of an outhouse. . . but was brought to Drishane House by Colonel Somerville in about 1880, for safe keeping.

This is one side of the Bluid Stone (both sides are covered in cupmarks), which is housed at the Cork Public Museum

The other two pieces are from the townlands of Gortbrack, immediately to the west of Farrandau (the townland in which Knockdrum Fort is situated) and Bluid (either East or West) which is to the west of Gortbrack. Gortbrack is in the Stone Corridor at University College Cork, and the Bluid stone (an unusual two-sided example) is at the Cork Public Museum. Both had been in the possession of Boyle Somerville, and were presented to UCC after his death. They had been brought to him by local farmers who knew of his interest in such things. We can only lament that of the six separate examples of rock art known from this immediate vicinity, we can be reasonably confident that only one, the Giant’s Grave, is in its exact original location. Neither of the two pieces at Knockdrum Fort are precisely where they were found, but at least they do not seem to have been moved more than a few metres from their original situations.

There is scope for much more investigation of this intriguing group – we shall call it the ‘Boyle Somerville Rock Art Concentration’. But for now, let us once more raise a toast to Boyle, pioneering archaeoastronomer of West Cork.  His legacy lives on.

South West of Skibbereen lies a deeply indented section of the coast known as Castle Haven. It is perhaps best known for the town that clings to the steep hill on its west side – Castletownshend. We have written much about Castletownshend itself, about Edith Somerviille and about the lovely St Barrahane’s Church and its Harry Clarke windows. But the whole inlet is an explorer’s paradise, yielding up its treasure to us on successive visits so this post will be about other things to see around the Haven.

Castle Haven

Catle Haven on a misty day. The inlet was guarded by two castles: this one at Raheen and another at the entrance to the Haven

The Haven is shallow at its top end, but up to the spit of land that runs across it near Reen Pier, it provides a deep and sheltered harbour for boats, and a popular sailing ground. We like to drive down the road that runs above the eastern side of the Haven. It’s twisty and a bit treacherous but at a certain point it presents a view of the whole inlet, dominated by Raheen Castle.

Raheen Castle

This was a castle of the O’Donovan clan, built in the late 16th or early 17th century. It didn’t last long – it was attacked by Cromwellian forces in 1649 and the collapsed upper stories may be the result of cannonball damage.

Raheen Corner machicolation

Continuing to the end of the east side brings you past Reen to the wonderful harbours of Myross and Squince, but that’s a post for another day. Now we’ll return to the west side of the inlet and visit two spectacular archaeological sites, Knockdrum Fort and the Gurranes Stone Row, before proceeding down into Castletownshend.

Knockdrum interior and views to north

To get to Knockdrum Fort, you have to park at the large church about 2km before the village. Walk downhill about half a kilometre until you get to the signposted green road to the fort. A pleasant trudge brings you to a set of steps and these lead up to the site. This is an excellent example of an early medieval stone fort – the kind of fortified homestead that marked the residence of a family of high status before the Normans taught us how to build tower houses.  From this site there are striking views across Castle Haven.

Entrance to Knockdrum

But there’s more to this place than just the fort. There’s an early Medieval cross slab just inside the entrance, and a fine example of 4000 or 5000 year old rock art just outside it. There’s another piece, a cupmarked stone, inside the fort, lying on the ground. All three are here thanks to the activities of Boyle Somerville, a keen amateur archaeologist and brother of Edith Somerville who lived in Drishane House, just below the fort. Farmers who found such items would bring them to him and he placed them here for safekeeping. Also inside the fort you will see evidence of a souterrain – an underground passage used for storage when the fort was active.

Knockdrum cross slab

If you look north across the valley once at Knockdrum you will see a stone row on a nearby hill. These are the Garranes ‘Fingers’. (They are on private land so you should seek permission to visit and make sure there are no bulls in the fields.) The best way to access them is to tramp through the fields across the road from the entrance to Knockdrum. It’s well worth the effort – once you get up to them you will see that more uprights are now lying on the ground. This was originally an alignment of at least five stones, unusually tall and thin, positioned so that they would be visible on the skyline from many directions.

Gurranes Fingers

Drive down towards the village now, until you get to the entrance to Drishane House. To the right of the gate is a bench dedicated to Boyle Somerville. In 1936 he was shot dead by the IRA, who claimed he was recruiting local young men for the British Navy. He was liked and respected locally and, outraged by the deed, the people of Castletownshend raised money for this memorial. If the house is open (there will be a sign) this is a wonderful place to visit. For a small charge you can wander around the extensive grounds and visit the Edith Somerville Museum. We love to go in spring, when the bluebells provide a vivid carpet and a photographer’s paradise.

Down to the village now and up to the church. But this time, instead of heading inside to see the Clarke windows, or behind the church to view the graves of Somerville and Ross, cross the graveyard until you find a gate at the far side and head east along the edge of the field towards the water. There you will find the remains of a structure labelled as a star-shaped fort on the OS map. Nowhere near as enormous as the massive star-shaped Charles Fort in Kinsale, nevertheless it is a reminder of a time when the sleepy village was not as peaceful as it is now. Dating to the 1650s, not a lot remains, just enough to confirm that this was a structure built for defence. Along the way you might also see a ruined square tower, known as Swift’s Tower. This was built as a belvedere, (a place to admire the view) and legend has it that Dean Swift visited and liked to write there.

Left is the remains of a bastioned fort, labelled as a ‘Star-Shaped Fort’ on the OS map. Right is the belvedere, where Swift is said to have written

Drive back out of town now and take the left turn after the entrance to Drishane House. Follow this road for about a kilometre to a sharp left turn, just before a small crossroads and turn left down a narrow road that ends at the sea. A tower house used to guard this part of the Haven but nothing remains of it now except a stump covered in ivy and brambles. But wander around the graveyard and admire the picturesque siting of the old church, already in ruins by the mid-1600s. This is a good example of a classic West Cork graveyard. Most graves are marked by simple stones at the head and foot, with no inscriptions. 

Castlehaven Graveyard atmosphere

There are some family plots and some more elaborate memorials, including one for Ellen Buckley, second wife of O’Donovan Rossa (although his name, interestingly, does not appear on the headstone).

Castlehave graveyard, old church

To the immediate left of the graveyard you will find a stile leading to a green path. Take this path and walk up though the luxuriant woods past a rushing stream until you come to a little wooden bridge.

Path by the stream

On the other side is a holy well, cut into the hillside and decorated with ribbons and fishing floats. Make a wish, or say a prayer – this is a special place and still visited and maintained by local people.

Take OS Discovery Map 89 with you. Most of the sites I describe are actually marked on it. But if you get lost, have fun, and let us know what you discovered!
