The main panel of art within Cairn L is lit up with a beam of light, which penetrates the chamber not long after sunrise in early November and Feburary. Cairn L, Loughcrew November 1995.
Loughcrew is the home of a superb collection of megalithic art; many of the stuctural stones of the chambers bear engravings, and doubtless there were many more in the past. Eugene Conwell, who 'discovered' Loughcrew while on a picnic with his wife, had a few of the stones illustrated for his lectures to the Royal Irish Academy. The Hag's Chair, left is one of his illustrations. The Dutch artist du Noyer recorded many of the Loughcrew engravings in the 1860's, a very valueable record since many of the stones have greatly weathered since then. Two of his illustrations are reproduced below. More of Du Noyer's illustrations can be seen in Michael Herity's 1975 book Irish Passage Graves.

Excerpt from Pagan Ireland by Wood-Martin.
What the peculiar marking called 'rock-scribing' represents is a question still unanswered, though numerous conjectures have been hazarded. Cup - markings, incomplete rings, a series of circles round a central cup ó sometimes with a radial groove through the circles ó these are the commonest types. It has often been advanced that these incisions in the hard rock could only have been produced with metallic implements, but it is stated that a person experimenting, with only the assistance of a flint chisel and a wooden mallet, cut, in the space of two hours, nearly an entire circle on a block of granite which bore archaic devicess.
The megalithic chambers in the carns on the hills over Loughcrew, County Meath, are more lavishly adorned with types of primeval sculpturing and devices than those at present known in any district except France, for Ireland possesses a collection of this species of pre-historic ornamentation which, in singularity, number, and quaintness of design, is approached in point of interest only by some of the great stone chambers of the district of the Morbihan. In Ireland, cup-markings appear to be the commonest form of ornamentation, and they present two leading varieties, i.e. circular hollows of more or less depth, and of a diameter varying from eighteen inches to as little as one inch. These depressions sometimes occur singly, but usually they are in groups; not unfrequently around, or partly enclosing each, may be observed one or more incised lines, often of considerable depth, to which other markings and variations are occasionally added. Somewhat similar rock-scribings abound in Yorkshire, in Northumberland, on the Cheviot Hills, near Edinburgh, and in the Orkneys. Various attempts have been made to decipher their meaning. The Right Rev. Charles Graves, Bishop of Limerick, propounded the theory that these circular rock-carvings were rude maps of raths, and observes:
'It was to be presumed that the persons who carved the inscriptions intended to represent circular objects of some kind; but what could these objects have heen? Some have suggested shields. This notion seems incon-sistent with the fact that the same stone presents so many circular symbols of different sizes, varying from the small shallow cup of an inch or two in diameter to the group of concentric circles two feet across. It also seems probable that, as shields, in general, used to bear distinctive devices, these would reappear in the inscriptions; but the inscribed circles exhibit no such variety as might have been expected on this hypothesis. Again, if the circles represent shields, what could be meant by the openings in the circumference of many of them. Lastly, what connexion could there be between the idea of shields and the long lines appearing in the Staigue monument, or the short lines on that of Ballynasare? '
Another idea was, that these figures were designed to represent astronomical phenomena. This notion was perhaps the most obvious, and the least easily disproved. It harmonizes also with what has been handed down respecting the elemental worship of the Pagan Celts. Nevertheless it seems open to obvious objections. In astronomical diagrams, one could hardly fail to recognize a single symbol conspicuous amongst the rest as denoting the sun or moon, or two such symbols denoting both these bodies. One might also expect to see some delineation ó even by the rudest hand ó of the phases of the moon. We look in vain for these indica- tions of an astronomical reference in the groups of lines and circles. Again, this supposition fails to account for the openings in the circles, and the lines which appear in connexion with them.'
Conwell's engraving of the elabourate right hand recess in Cairn L, from about 1870.
It has been suggested that these circles were intended to serve as moulds in which metal rings might be cast. This explanation is decisively negatived by the fact that the circle occurs on parts of the rock which are not horizontal. Another proposed idea is that the circles were used for the purpose of playing some game. The great dissimilarity which exists between the figures on the different stones renders this explanation unten- able. The theory which appeared the most probable, was that the circles were intended to represent the circular buildings of earth or stone of which traces still exist in every part of Ireland. This conjecture was supported by the following considerations:
Conwell's engraving of the Hag's Chair at Cairn T, from about 1870.
'The circles are of different sizes; and some of them are disposed in concentric groups. The dwellings and fortified seats of the ancient Irish were circular; they were of various sizes, from the small cloghan or stone- house often feet in diameter to the great camp, includ- ing an area of some acres; and the principal forts had several concentric valla. The openings in the inscribed circles may have been intended to denote the entrances. The other inscribed lines may have represented roads passing by, or leading up to, the forts.'
Conwell's engraving of a passage stone in Cairn T, from about 1870.
The conjecture that these carvings were primitive maps, representing the disposition of the neighbouring forts, appeared to be a fanciful one, and the drawings were laid for many years on one side ; finally, however, Bishop Graves having re-examined this subject, came to the conclusion that his original theory was correct, that the centres of the circles and the neighbouring cups and dots arranged themselves, generally, three-by-three; in straight lines, or approximately so, and that the ancient raths marked on the Ordnance Survey maps appear, to some extent, to be also arranged three-by-three in straight lines.
Another class of 'rock-scribings' consists of scorings, such as are found upon the flagstones of sepulchral carns, as at Lough Crew, Dowth, and New Grange. There is also a class of irregular scorings, some of which may be genuine Ogham, although roughly and irregularly executed, whilst others are of a character which precludes their classification under this heading.
Some of the so-called ' cup-markings ' on sepulchral monuments have been caused by the action of Nature, being the well-known ' ripple marks ' common in the old red-sandstone series; but anyone familiar with geological formations would not confound the artificial with the natural work, though depressions ó very like genuine 'cup-markings' ó are created on the upper surface of calcareous rocks by the solvent action of rain-water; but even ignoring the undoubted traces of the pick or pointed instrument occurring on some of the 'cup-markings,' it is impossible to suppose that the concentric or spiral rings, which frequently surround the ' cups,' could be the result of geological causes.

'We shall, I think,' remarks H. M. Westropp, who advances a very simple theory as to their formation, ' be led to a more just conclusion as to their origin, if we bring before our mind that the savage and primitive man has the same fondness for imitation, the same love of laborious idleness as the child. A child will pass hours whittling and paring a stick, building a diminutive house or wall, and tracing forms on the turf. The savage will wear away years in carving his war-club and polishing his stone-adze. These considerations lead me to attribute these carvings and sculpture to the laborious idleness of a pastoral people, passing the long and weary day in tending their flocks and herds ; they amused themselves by carving and cutting those various figures, and the rude outlines of primitive men, in various countries, like the rude attempts at drawing by children, cannot but bear a family resemblance to one another, their utter absence of art being frequently their chief point of relationship.'

W. F. Wakeman thus depicts another aspect in which these rock carvings may be regarded: ó ' Many men of ancient and modern times, confined by necessity to a listless existence, in an inhospitable region, might very naturally have beguiled their hours by carving with a stone, or metallic instrument ó such figures as their fancy prompted ó upon the nearest object which hap- pened to present a surface more or less smooth. Scorings or designs made under such circumstances, would be, in character, as various as the skill or humours of their authors. Now, when in many districts of the country, and some of them widely apart, we find upon the sides of caves and rocks, and within the enclosure of Pagan sepulchral tumuli, a certain well-defined class of engravings, often arranged in groups, and with few exceptions, presenting what may be styled a family type, we can hardly imagine them to be the result of caprice.'
Some 26 stones within Cairn T bear decoration, most notably the backstone of the end-recess (Elizabeth Twohig's illustration is shown, right). American researcher Martin Brennan demonstrated in the early 1980's that the equinox sunrises illuminate this complex slab of megalithic symbols. This is Brennan's great contribution to Irish megalithic research: how the engravings interact with the beams of light and by extension the heavenly bodies. Brennan's groundbreaking book, The Stars and the Stones has line drawings of many of the engravings at Loughcrew. The book has recently been re-published as the Stones of Time.
The only surviving engraved kerbstone at Loughcrew, the Hag's Chair (top photo and drawing, left), is positioned on the north side of Cairn T. The engravings are very much weathered today, and not obvious at all on the stone except for some relatively recent graffiti. The picture above shows the kerb art highlighted using Conwell's engraving of the Hag's Chair.
Cairn U also has several engravings within it's chamber, including a long set of inverted nested arcs on the backstone, which may represent a sunrise. The stones in the recesses on either side also bear interesting compositions. There are scattered engravings on the other monuments, which can be found by a careful search in good light, but not a great amount remains.

On Cairnbane West, the largest number of surviving stones are within Cairn L, with it's unique standing stone and basin. A beautiful and dramatic design of nested circles, cupmarks and arcs covers the slab at the rear of the main right-hand recess, below and top picture. This design seems to me to have much in common with the art and basin in Knowth west in the Boyne Valley to the east. The northmost slab of the recess is covered with a complex set of orbiting bodies and seems to be a diagram depicting a cosmic event, such as the eclipse postulated by Paul Griffin.

There are a number of other carvings in this chamber. Brennan believes the set of squiggles on the keystone at the back of the chamber represent the movements of the late summer full moons. Brennan demonstrated that this engraving is illuminated by the rising sun on the November and February cross-quater days. This stunning display of light and shadow is illustrated on the top of this page. Aside from L, carvings can easily be found in Cairns I, H and xF.
Engraved medieval bone slip from Cairn H.
Hundreds of bone slips were discovered in Cairn H, during Raftery's excavation in 1943, and several are now on display in the National Museum in Dublin. They date about 3000 years after the cairns were built. It is easy imagine the Iron Age or medieval artists at work, inspired by the ancient engraved spirals on the walls around them. There are several ringforts, a few cashels and a fine ceremonial rath with a souterrain close by.

The archaeologist Elizabeth Twohig took rubbings of the Loughcrew stones (seemingly with the exception of the Hag's Chair), and her 1981 book, the Megalithic Art of Western Europe is essential to anyone who wishes to locate and study all the designs on the engraved stones.
Engraved stone on Kingsmountain about 4 km east of the Loughcrew Hills. The stone is about 3 meters tall and has four large, well picked spirals. It is thought to be the remaining stone of a destroyed mounument. Patrickstown Hill is visible from the stone.
There is more art in the area. A standing stone on the south slope of Sliabh na Caillí has an engraved spral on it's north surface. An engraved slab was recently erected within the entrance on the way to Cairnbane West. There appear to be engraved slabs near the Ballinavally stone circle to the north of the hills. A lone slab engraved with large spirals stands on King's Mountain a few km to the east. Finally, at least one Loughcrew stone is on display in the National Museum in Dublin.

Researcher Michael Poynder believed that the engravings were illustrations of the earth energies that flow through these sites. Certainly the engravings are found at key locations throughout the monuments. Loughcrew is located on a line that passes through the Hill of Howth, with a large dolmen on the top, the Hill of Tara, and continure past Loughcrew to Sliabh da Ean and Knocknarea in County Sligo.
