Knowth Kerbstone K90

Kerbstone K90 is one of the 127 kerbstones numbered in Professor George Eogan's record of the Knowth monument. It is located on the north-western side of the great passage tomb mound.

Over 200 decorated stones were found during excavations at Knowth. Much of the artwork is found on the kerbstones, particularly approaching the entrances to the passages. Many of the motifs found at Knowth are typical: spirals, lozenges and concentric circles. However, the megalithic art at Knowth contains a wide variety of images, such as crescent shapes. Interestingly, much of this artwork was carved on the backs of the stones. This type of megalithic art is known as hidden art. This suggests all manner of theories as regards the function of megalithic art within the Neolithic community who built the monuments in the Boyne valley. It is possible that they intended the art to be hidden. It is also possible that they simply recycled the stones and reused the other side.

Excavations at Knowth Volume 7: The Megalithic Art of the Passage Tombs at Knowth, Co. Meath

The complex of passage tombs at Knowth is dated c. 3200–2900 BC, and this volume deals with one of the most significant aspects of the site. It presents a complete catalogue of the 390 recorded carved stones at Knowth, through descriptions, drawings and photographs.

Six main styles of art have been identified and these are discussed, together with the motifs and techniques employed. The Knowth carvings constitute c. 46% of all such art in Ireland, and the volume sets the Knowth art in the context of the other Irish carvings, those in western and northern Britain, and also the somewhat earlier art found on megalithic tombs in Atlantic Europe.

Knowth Stone Age passage tomb

K90 forms part of the ceremonial kerb documented during decades of excavation at Brú na Bóinne by Professor George Eogan and his team. One hundred and twenty-four kerbstones still ring the base of the Great Mound, defining an oval plan roughly 80 metres east-west and 95 metres north-south. Many carry carved spirals, lozenges, concentric circles and other abstract motifs that can be viewed on a circuit of the mound (kerbstone gallery).

Roughly half of all Irish passage-tomb art and about a third of the megalithic art of Europe comes from Knowth. The carvings share a distinctive Boyne Valley style that links kerb, passage and chamber stones into a single artistic tradition (Excavations at Knowth Volume 7).

The mound cannot be visited independently. Access is by guided tour from the Brú na Bóinne Visitor Centre at Donore, on the south bank of the Boyne, with a shuttle bus to the site and interpretation by trained guides.

The first farmers reached the Boyne Valley around six thousand years ago, probably travelling by river. They cleared woodland, cultivated wheat and barley on rich soils, and kept herds of cattle, sheep, pigs and goats before committing enormous communal labour to the great tombs.
