The crozier is 115 cm high and built from a wooden core, with added
copper-alloy plates containing silver, gold,
niello and glass. It is almost fully intact and in relatively good condition with little modern reworking. The decoration and patterns across the object are influenced by
Viking art, particularly the contemporary Urnes style, which is characterised by slim and stylised animals interwoven with tight patterns. The art historian
Máire de Paor described it as showing, like the Crozier of Dysert O'Dea, the "Irish-Urnes in its full development".
Shaft, knops and ferrule Its shaft is made from
oak wood and contains three knops, the lower of which is cast into the
ferrule (foot or base). This area is decorated with cast panels with
zoomorphic figures, as well the heads and full figures of humans, the latter of which have been compared in style to the 7th- and 11th-century Bearnan Chulain shrine. The upper knope contains holdings for insert panels, which are lost. Unusually for medieval croziers, the ferrule is fully intact and in place: the Dunloe and
Clonmacnoise croziers are the only other surviving examples that have retained this element. The Lisomore ferrule contains
openwork patterns terminating with three legs.
Crook and drop The crook was cast as a single piece on a mostly hollow wooden core. The crook is decorated on both sides with blue glass studs placed within gold collars that hold white, blue and red
millefiori glass insets. The missing panels probably contained gold filigree, while the drop once held semi-precious stones fixed within gold collars. The crest contains a procession of three open-jawed animals terminating in another animal head with blue eyes. The front of the drop contains zoomorphic interlace panels, but is missing its original gold-foil border. During refurbishment at the NMI in 1966, two small relics were found in the interior of the drop and crest's base, although they are probably secondary (i.e. added later). The reliquary inside the crest consists of a piece of wood, measuring 31
mm in length, 16mm in width and is 6mm deep. The reliquary within the drop is slightly larger (width: 22mm, length: 18mm, depth: 15mm) and comprises a single sheet of
copper-alloy folded into a box containing "tiny slivers of wood". It is thin enough that it would have been slid in as an insert into the drop's side. A piece of woven
linen cloth measuring 40mm x 23mm was also found during the opening of the crook, and may have been a
brandeum, i.e. placed to represent the
Holy shroud. ==Inscriptions and dating==
