Thanks to K Owen for this interpretation of the panel of interlacing on the front of the Ulbster Stone, a Pictish cross-slab in Caithness. More to follow ….
Interlaced knotwork of some major Pictish cross slabs found in Scotland, based on triquetra knots
By K Owen
The Living Field welcomes this article and drawings from stone-carved monuments left by early mediaeval people based in and around the lowland croplands and grazing lands.
Aberlemno Kirkyard Stone, early 8th Century, Angus
The Aberlemno Kirkyard Stone is an impressive sandstone slab 2.29 m high, 1.27m wide with stone carved interlacing and fantastic beasts on Face A and the carving of the depiction of a battle scene on Face C. This is from Face A, showing the north quadrant of interlacing that forms the upper part of the cross. The stone had been damaged, so there had to be a bit of interpretation of what it should look like, using the other shapes within it and with reference to similar carvings [1, 2].
The stone now stands in the grounds of Aberlemno Church, itself within a landscape that has sustained crops, livestock and trees over thousands of years. The view of arable and grass fields (upper image, below) was taken from the ‘fort’ on Turin Hill, a few km to the south of the church.
Kilduncan Cross Slab, 10th Century, Fife
The cross slab was found in 2001 lying against the wall of a barn in Kingsbarns, Fife. It is now in St Andrew’s Museum. It is a small slab, only 0.78m high and 0.53m wide. There are two S-dragons carved on the face, framing a circle, with carved interlaced knotwork in the centre of the stone.
Eassie Cross Slab, 8th Century, Angus (near Glamis)
This great stone is an old red sandstone cross slab 2.03 m high and 1.02 m wide. It is protected within the ruins of the Eassie old parish church by purpose-built screens. There are four quadrants to the cross, each with carved interlaced knotwork, together with hunting scenes and angels. This is the west quadrant of the cross.
The ruined church lies several km west of Glamis. Images below show the church in 2021, the cross slab under its protective cover, and a nearby view of spring-sown crops just emerging green from the soil, tree lines and forest plantation beyond.
Ulbster Stone, 9th Century, Caithness
This once stood in an ancient burial ground attached to the ruined Church of St Martin at Ulbster near Thurso. Both sides of the slab are carved with strange beasts, symbols and interlacing. This drawing of interlaced knotwork is taken from the north quadrant of side A but all the quadrants are based on four triquetra knots.
St Vigeans 1 – Drosten Stone, 9th Century, Angus
This remarkable stone stands 1.84 m high and 0.55 m wide in St Vigeans Museum near Arbroath. On the face shown in the photograph below there are a number of carved animals – a doe with a suckling fawn, a bear, an eagle feeding on a salmon, a horned animal and an archer with a bow.
Images below, taken inside the museum show a description of the stone, the stone itself and (inset) a closer view of some of the animals, including ‘a beast with a large curved horn on its head and its tail curved over the back’ .
The Boar Stone of Gask, 9th Century, Perthshire
This old red sandstone slab is 1.88 m high and 1.08 m wide and is now found in the grounds of Moncreiffe House. The lower shaft of the cross has this carved interlaced knotwork while carvings of animals such as deer and boar surround it.
