_Iniscaltra._--The principal church in the monastic establishment founded by St. Caimin in the seventh century on Iniscaltra, in Lough Derg, was re-edified by Brian Boru (died 1014), the buildings having suffered the usual fate of destruction by the Danes. The chancel of the church is the work of that king, and the nave also was restored. The west doorway--a fine work though now much decayed--consisted of three concentric semicircular arches, ornamented with chevron mouldings in hollow lines. ‘The piers of these arches were rectangular, but rounded at their angles, so as to form slender semi-cylindrical shafts, with angular mouldings on each side, and having in capitals well-shaped human faces carved in low relief.’ The chancel-arch consists of three receding and concentric plain arches, the piers being rounded into semi-columns with carved capitals. * * * * * _Killeshin._--The church of Killeshin, in the Queen’s County, lying at a distance of about two miles from Carlow, appears to have been one of the most beautiful structures of this class ever erected in Ireland. Its doorway, until very lately, retained, in a remarkable degree, the original sharpness of its sculpture. We were informed that, many years ago, a resident in the neighbourhood used to take pleasure in destroying, as far as lay in his power, the interesting capitals here represented; and that to his labours, and not to the effects of time, may be attributed the almost total obliteration of an Irish inscription which formerly extended round the abacus, and of which but few letters at present remain. The church of Killeshin is, perhaps, late in the style of the period. The arches, of which there are four concentric, forming the doorway, display a great variety of ornamental detail, consisting of chevron work, interlaced pattern, heads, &c. A pediment surmounts the external arch, and a window in the south side-wall is canopied by a broad band, ascending and converging in straight lines. A window of similar construction appears in the round tower of Timahoe, and ornamentation similar in style to the above appears on its fine doorway.
