The bronze casting (fig. 1) was recently purchased by the Royal Irish Academy. It was one of the antiquities preserved at Killua Castle, co. Westmeath, but its previous history is unknown. The length of the casting is 4·4 in.: the raised box-shaped portion is 2·4 in. in breadth, while the flat portion measures at its widest part 1·5 in. Possibly it was the limb of a cruciform mounting for a book-cover. Its ornamentation is admirable.
