From Ilkley town centre take the road up to White Wells (ask any local if y’ can’t find it), but instead of heading up the track to the wells, keep on the road and, after just over 200 yards, turn left up the Keighley Road.  Half-a-mile up there’s a dirt-track on your right which leads to Silver Well Farm.  Walk along here for about 150 yards, keeping your eyes peeled for a large rock in the heather about 50 yards up onto the moor.  You’ll find it.

Archaeology & History

Located just 100 yards west of the old Roman road that effectively runs north-south through the middle of Rombalds Moor and which, when this carving was executed, was a prehistoric trackway, this is an impressive carving, all but unknown by many.  On my last visit to this stone—maybe 10 years ago or more—it was a cloudy day.  I know this from the fact that the design on the stone was difficult to see in its entirety.  But not anymore!  When the northern antiquarian Dave Whittaker came a-wandering this way a few years back,  the stone so overgrown in vegetation that the design was very difficult to appreciate and, like any healthy curious antiquarian, he wanted to know what the full carving would look like.  He enquired whether or not it was OK to uncover the stone from beneath its mass of heather to see the full image and, as far as we were concerned the idea was a good one.  And so, following in the footsteps of Beckensall, Currie, Chappell, me and a few others, he got stuck in!

Looking across the stone (photo by Dave Whittaker)

As you can see in Dave’s fine photos, the petroglyph is indeed a fine one.  It comprises mainly of four cup-and-rings, two of which are incomplete  The rings, as you can see, are very faint, whilst the cups, both in the rings and those outside of them, are notably deep; perhaps indicating that they were carved into many times over a long period.

One of the great petroglyphic pioneers, J.Romilly Allen (1882) seems to have been the earliest to record this carving.  Allen’s early sketch (below) was obviously drawn on a shady day, as it misses several of of the rings that are clear to see when the the daylight is just right.  It’s an easy mistake to make.  He wrote:

J.R. Allen’s 1882 sketch
Hedge’s 1986 sketch

“One mile south-west of Ilkley is a road leading over the top of the Moor…very appropriately as Weary Hill.  To the west of the road, and between it and the boundary-wall of Silver Well Farm, is a small boulder of gritstone with cup-markings on it.  It lies at a level of 900 ft. above the sea, and it measures 8ft by 5ft.  On its upper surface, which is nearly level, are carved ten cups, varying in diameter from 2 to 3 ins., one of them being surrounded by a single ring.”

The pseudonymous “A. Reader” (1891) also included the stone in his international overview of prehistoric carvings, but merely copied the notes of his predecessors.  Nearly a hundred years later when archaeologist John Hedges (1986) did his survey of these moors, he described this carving simply as:

“Medium seized rock…in grass, heather and crowberry with c.ten cups, four with rings, two with grooves from rings, three depressions and series of probably natural lines running down to bottom edge.”

And as with the pseudonymous A. Reader (1891), Boughey & Vickerman’s (2003) also just copied Hedges’ earlier description.

Seeking numeracy in Alan Davis 1988 sketch
And from another angle (photo by Dave Whittaker)

The greatest analysis of this carving to date is by physicist and mathematician Alan Davis.  He set out in 1983 to explore the possibility of there being a universal measurement used in neolithic times that was coded into our cup-and-rings—a theory first espoused by the great archaeo-astronomer Alexander Thom. (1968)  He selected carvings from Rombalds Moor and Northumberland, including this one at Weary Hill (calling it the I/1 carving) to see if a ‘megalithic inch’ (MI) that was propounded by Thom had any foundation in fact.  As a mathematician he was ideally qualified to examine this proposition.  His 1983 paper found there to be “substantial support” for this prehistoric megalithic inch.  However, in a subsequent 30-page analysis of the same carvings Davis (1988) found that some criteria in his initial investigation needed re-examining.  In his updated report he told that “many of these deficiencies have now been remedied.”

His initial 1983 report concluded the Weary Hill carving possessed a deliberate mathematical code in accordance with Thom’s MI.  However in the subsequent 1988 report, Davis found that the measurements were based on 5MI and 3 MI, but only in the cup-and-rings and not the single cups.  Despite this, there remained an overall scepticism in terms of any deliberate universal use of the MI.  My own take on this is a simple one: there was no deliberate use of any MI at carvings.  Where we do find precise MIs, this is due simply to the average size of human hands, meaning that some obvious figurative correspondences will occur upon investigation.  The more you think about it, the more obvious it becomes.

Anyhow, all this intriguing geometry aside: to those of you who take the time to check this out, have a bimble in the heather barely 100 yards west and you’ll find a few other carvings sleeping quietly, whose site profiles I’ve yet to do…

East Wall Stone, Burley Moor, West Yorkshire

Cup-Marked Stone:  OS Grid Reference – SE 13924 45493

Getting Here

East wall stone on the right

Follow the directions to reach the impressive Woofa Bank prehistoric enclosure.  You need to find the walling that constitutes the enclosure itself and walk along to its eastern side where you’ll reach an ‘opening’, as if it may once have been an entrance at that side of the enclosure.  A reasonably large sloping rock is on one side of this ‘entrance’.  You can’t really miss it!

Archaeology & History

Unlike many of the other petroglyphs found within the Woofa Bank enclosure, the design on this one is faint — very faint indeed (much like the recently uncovered triple-ring petroglyph by the Thimble Stones).  Comprising simply of a small cluster of cup-marks, you’ll struggle to see this one — unlike its compatriot on the western wall of the enclosure.

Looking down on the rock
Some very faint cupmarks

It consists of a single cup-mark on the northern edge of the stone, whilst on the sloping southern part of the rock are a number of very faint cups, eroded by them there millenia of Nature’s wind and weathering.  One or two of the cups are just visible in good lighting, but what are almost certainly a few more can be seen when the rock is wet and in low daylight hours.  It’s a design that’s probably only of interest to the hardcore petroglyph fanatics, but without doubt this is yet another carving within this obviously important prehistoric enclosure.

West Dron Hill, Bridge of Earn, Perthshire

Cup-and-Ring Stone:  OS Grid Reference – NO 11845 15169

Getting Here

West Dron’s petroglyph

In the middle of Bridge of Earn village, take the Heughfield Road until, ⅓-mile on you hit the T-junction.  Turn left along Forgandenny Road and go along the curvaceous road for just over a mile where you need to keep your eyes peeled for the small left turn that takes you up the dead straight road.  At the top, turn left at the junction and go ⅔-mile, turning right at the next junction until after 400 yards you reach the houses on your right.  Go up the footpath opposite the houses (south) until, after nearly 400 yards, it splits.  Bear right and zigzag up the track for nearly a mile till you reach a large opening in the forest.  40 yards up the slope to your left is the stone—at last!

Archaeology & History

After the trail to get here, you might not be overly impressed by what you see – and it’s nothing special to look at to be honest.  But its location is a good one: reasonably high up on a sloping plateau which would have given good views were it not for the surrounding forestry plantations.  The only literary description of the site was the brief one in Discovery & Excavation Scotland, shortly after being rediscovered.  Mrs Johnson (1960) wrote:

Close-up of the carving

“A cup-marked stone was found by Mr. J. R. Morrison on the N side of West Dron hill.  The stone measures approx. 4ft long by 1ft 9in broad.

There are 17 cup-marks: five of which have channels, and two of which are joined in the form of a dumb-bell.  The stone lies with its longer axis NE-SW, and its broad face uppermost.”

Its seeming isolation is a peculiarity that I don’t buy.  Other carvings are going to be in the locale, probably on the same north- or north-east facing ridges – but due to the dense forestry, any other petroglyphs will remain hidden for quite some time…

Watcher Stone, Ilkley Moor, West Yorkshire

Cup-Marked Stone:  OS Grid Reference – SE 11816 46563

  1. Carving no.109 (Hedges)
  2. Carving no.263 (Boughey & Vickerman)
  3. White Wells 05

Getting Here

Watcher Stone by the path

From Ilkley, go up to White Wells (ask a local if y’ get stuck) and walk round the back of the building. Walk to the trees and then follow the footpath up onto the moors; but after 70 yards a small footpath on your right goes up the slope.  Take this and after about 90 yards it veers round to your left, following the contours up towards the copse of trees.  Another 100 yards up it meets with another path and once here, just yards in front of you, right by the side of the footpath, is the stone in question.

Archaeology & History

First described in John Hedges (1986) survey, this simple cup-marked stone typifies many petroglyphs on these moors: a barely visible design much eroded by centuries of wind and water, with markings perhaps only of interest to the devoted student and explorer.  But at least it’s a good place to sit, rest and watch the valley below.

Looking down at the cups
Hedges 1986 sketch

This old fella looks to have only five cupmarks on its supper surface, one of which is elongated, as shown in Hedge’s drawing.  However, when he saw this, he thought the elongated ‘cup’ consisted of three of them in a line, all linked up.  He saw a “medium sized smooth grit rock standing in grass, its surface triangular in shape, with flat top sloping slightly N to S.  Three cups connected by a groove, c. four other cups, all shallow and worn.”

This description was echoed in Boughey & Vickerman’s survey (2003), where they thought that the “triangular top surface has about seven worn cups, three connected by a short groove.”  But if the light isn’t quite right, this can be very difficult to see.

Castleton (7c), Cowie, Stirlingshire

Cup-Marked Stone:  OS Grid Reference – NS  8551 8819

Archaeology & History

Looking down on C-7c

Near the northwestern end of the small geological ridge that runs to the west of Castleton farmhouse, close to an awesome nine-ringed carving, we find this more simplified triple-ringed petroglyph.  And although the carving is easy enough to describe, its labelling (as ‘Castleton 7c’) is rather troublesome.  As with other carvings in this locale, the name of the stone is based on a survey done by Maarten van Hoek in the mid-1990s.  But van Hoek’s sketch of Castleton 7c and the one shown in our photos, whilst very similar, possess attributes that aren’t on van Hoek’s drawing.  Now this isn’t too odd, as many petroglyphs look different when lighting conditions change; to the point where some features you can see one day are almost invisible the next.  But this carving has attributes that are very difficult to miss – and van Hoek’s detailing tended to be good.  But, all this aside: until we can verify with certainty one way or the other and despite my suspicions that this isn’t what van Hoek described, I’m still entering this carving as Castleton 7c. So – now that bit’s out of the way…!

When we visited the site two years ago the day was dark and overcast, so we didn’t really have good conditions for seeing any faint carvings.  But this wasn’t faint, thankfully.  It was completely buried beneath soil and gorse bushes, but thankfully Paul Hornby managed to unearth the one you can see in the photos.  If it is the Castleton 7c petroglyph, it was rediscovered by van Hoek on one of his ventures here in 1985.

Carving showing wavy lines on right
…and from another angle

When we visited the site we only managed to uncover a small section of the stone, as the roots of the surrounding gorse prevented us from seeing more. (it’s tough stuff unless you’ve got the right gardening equipment!)  The section we uncovered consisted of a cup-and-triple-ring.  This is consistent with van Hoek’s sketch and description; but we also found there were two very notable ‘arcs’ on the outer edge of the rings—nearly opposite each other—as if another, fourth ring had been started.  You can’t really miss these elements – and even in the poor lighting conditions we had, these outer arcs are very evident on a number of photos – especially when they are expanded to full-scale.  However, as I mentioned, we were unable to uncover all the rock; but when van Hoek was here there was far less herbage.  What he saw on this carving was as follows:

“Deturfing part of this ridge revealed a fine cup with three rings with a broadly pecked tail; one solo cup; one large oval ring with small central cup; and a faint cup with two rings, the outer one incomplete.  The rock slopes 12º ENE.”

Crap drawing done in crap lighting
van Hoek’s 1996 sketch

The “broadly pecked tail” he mentions is also not really clear in any of the 60 photos we took.  There is a faint line that runs through the three rings, into the central cup and out the other side: a single curving line no less.  It’s certainly visible, but it’s far from broad.  But there are a number of other lines coming out of the rings.  These maybe just natural scratch marks, or even scratches acquired from farming activity.  It’s difficult to say.  In the poor light that we had, there as looked to be a single cupmark a few inches away from the rings, but this isn’t consistent with the position of the cupmark on van Hoek’s sketch.

There’s a simple solution to all this: we need to revisit the site and expose more of the rock.  At least that will tell us once and for all whether this is the same as van Hoek’s stone, or whether we’ve found yet another new carving. Watch this space, as they say! 😉

Table Stone carving (photo by Jonathan Warrenberg)

From Ilkley walk up to the White Wells and follow the footpath behind it up to the cliffs, up the stone steps and onto the moor itself.  Once you’ve climbed the steps, walk uphill onto the moor for 100 yards, then turn right up a small path for another 80 yards until you reach the large Coronation Cairn with its faint cup-and-ring stone.  From here there are two paths heading west: take the higher of the two for just 30 yards where a small group of rocks are by the path-side on your right.  The curiously-shaped ‘upright’ one is the stone in question.  You’ll see it.

Archaeology & History

Found high up on top of an oddly-shaped stone, somewhat like an anvil or small table (hence the name, courtesy of Jonathan Warrenberg), is carved a slightly worn, incomplete cup-and-double-ring.  This aspect of the design is the one that stands out the most; but you’ll also see a cup-and-half-ring there too.

The carving seems to have been described for the first time in John Hedges (1986) survey (though I may be wrong), who described an additional feature to the design, saying:

“Small grit rock in possible cairn material, cut all round as if one pedestal, top surface triangular, sloping slightly SW to NE, overlooking Wharfe Valley, in grass and crowberry.  Large cup with two vestigial rings, second large cup with vestigial ring.  Possible third ring of corner edge (hewn off).  Recent carving of initials spoils original carving.”

John Hedges 1986 sketch
Looking from above (photo – Jonathan Warrenberg)

His description of the stone being “in possible cairn material” doesn’t seem true – although a number of petroglyphs are associated with cairns of varying sizes.  Several other carvings can be found close to this one.

In Boughey & Vickerman’s (2003) later survey, they copy Mr Hedges earlier description, but with less detail.

The view from this stone is quite impressive.  Even with the minor tree cover that would have existed when this carving was done, you’d still have clear views up and down the winding wooded valley that was carved by the River Wharfe.  The moors to the north at Denton and Middleton with their own petroglyphic abundance could be chanted at with ease from here when the winds sleep.  Tis a good spot to sit… if you’re lucky enough to get some silence…

Castleton (5f), Airth, Stirlingshire

Cup-Marked Stone:  OS Grid Reference – NS 85584 88087

Archaeology & History

As with other carvings in this locale, the name of the stone is based on a survey done by Maarten van Hoek. (1996)  It’s a pretty simplistic design within the impressive Castleton complex, found at the southeastern end of the gorse-covered rocky ridge, about 70-80 yards west of the farmhouse.  It was uncovered on a visit here by Nina Harris, Paul Hornby, Frank Mercer and Lisa Samson on Sunday 19 November, 2018.

The cup-marked stone
Large cup & arc of 3

Unlike the others in the Castleton complex, this carving is probably of interest only to the hardcore petroglyph hunters.  The design consists of at least ten cup-marks on the uncovered section of the rock, one of which appears to have a broken circle with two ‘entrances’ either side of it, so to speak.  The most notable element in the design is close to the edge, where an arc of three cups almost corners a larger cup right at the edge.   There may be more carved elements to be found on the westerly side of the stone, which was covered in deep vegetation when we came here.

X supposedly marks the spot

Out of Aberfeldy, take the A826 road as if you’re going up Glen Cochill.  Not far up, just where the housing of Aberfeldy itself ends and the green fields open up either side of you, keep on the road for a half-mile where you meet a small copse of trees on your left, with a dirt-track that runs down the slope.  Go along the track for 0.8 miles (1.3km), past the Ursa Major Stone and where the track splits, go left past the Quartz Stone and follow the track through the farmyard.  It’s somewhere there – or is supposed to be!

Archaeology & History

On our visit here, we couldn’t locate the cup-and-ring stone that’s described in Sonia Yellowlee’s (2004) regional rock art survey.  She described it, as archaeologists always do, in the briefest manner, telling us simply:

“Leaning against a pile of rubble in the farmyard there is a split boulder bearing eighteen cupmarks, one of which is ringed.”

It may have been destroyed, as we were told by a couple of locals that there used to be “a real miserable sod” living there.  When we visited the place and tried to ask the present farm owner, sadly he wasn’t to be found.  If any rock art explorer manages to locate this seemingly lost cup-and-ring, please let us know – and mebbe send us some photos so that we can add them to this site profile. 😉

The cupmarked Quartz Stone

Out of Aberfeldy, take the A826 road as if you’re going up Glen Cochill.  Not far up, just where the housing of Aberfeldy itself ends and the green fields open up either side of you, keep on the road for a half-mile where you meet a small copse of trees on your left, with a dirt-track that runs down the slope.  Go down here and follow the slightly meandering track for 0.8 miles (1.3km), a short distance past the Ursa Major Stone where the track splits.  Take the track to the left and there, less than 100 yards on you’ll hit a large boulder on your left.  That’s it!

Archaeology & History

Not previously recorded, this simple cup-marked stone will probably only be of interest to petroglyph aficionados, or those folk who are into  ‘energies’ at sites.  This latter aspect is due entirely to the carving being etched onto a huge rock, much of which is composed of quartz—which isn’t too unusual in this part of the world.  But that aside…

Looking down at the cups
The cupmarks highlighted

It is one in a group of carvings within a few hundred yards of each other, with its nearest neighbour 20 yards to the north.  That one’s covered in cups—but on this large Quartz Stone, only two of them exist, on the top near the centre.  Just a couple of inches across and half-an-inch deep, they’re pretty clear once you see them.  The raised piece of ground behind the stone is artificial and has variously been described by antiquarians and archaeologist alike, as either a prehistoric dun, or a stone circle.  Whatever it may be, some of it is certainly man-made.  Check it out – and mebbe ask the friendly fat fella who lives nearby and what he thinks.

The stone from the trackside

Out of Aberfeldy, take the A826 road as if you’re going up Glen Cochill.  Not far up, just where the housing of Aberfeldy itself ends and the green fields open up either side of you, keep on the road for a half-mile where you meet a small copse of trees on your left, with a dirt-track that runs down the slope.  Go down the track, bending to the right, then the left and then on for a quarter of a mile until the lines of trees appear either side of you.  Barely 200 yards along, the track swerves slowly to your right, and the field above you slopes uphill.  Keep your eyes peeled at the fencing on your right and you’ll see a stone sloping towards you right by the fence with faint cup-marks on it.  You’ll find it!

Archaeology & History

A truly fascinating cup-marked stone recently uncovered by Paul Hornby on another one of our TNA meanderings. Fascinating because of the curious arrangement of the cups on the stone.  Often, cup-marked stones have little to interest the causal visitor – but this one’s different.  As can be seen quite clearly, the cups are arranged in the shape of the constellation of the Great Bear, or Ursa Major – albeit with an extra ‘star’ in this design.  But it’s damn close!  In all likelihood (he says with his sceptical head on 😉 ), the design is fortuitous when it comes to the Ursa Major.  I know from many years experience how easy it is to see meaningful shapes and designs in the almost entirely abstract British petroglyphs, but the design is very close to the constellation we all got to know when we were kids.

Looking along the stone
Gazing down at Ursa Major

The stone itself slopes upwards at an angle of about 60º, before starting to level out as it rises.  All of the cup-marks have been pecked onto this sloping surface (the vast majority of carvings are found on top of stones).  Altogether, at least twelve faint and shallow cups were exposed when we looked at it—measuring the usual inch to inch-and-half across—but it is likely that more of them are hidden beneath the turf at the top of the stone.  We could discern no rings or other features in the design.

This is just one carving amidst a good cluster of petroglyphs within a few hundred yards of each other (the Quartz Stone being one of the nearest) that are well worth checking out if you like your rock art.  It may also be of interest to astronomy students, or those exploring archaeo-astronomy.
