Kildare is the only religious establishment in Ireland which preserved down to a comparatively recent period the double line of succession, of abbot-bishops and of abbesses, and what is more, the annalists take care to record the names of the abbesses as well as of the abbots. This, no doubt, arose from the fact that at least in public estimation the lady-abbesses of Kildare enjoyed a kind of primacy over all the nuns in Ireland, and, moreover, were in some sense independent of episcopal jurisdiction, if, indeed, the Bishops of Kildare were not rather to some extent dependent on them. St. Conlaeth was not only a scholar and a bishop, but also a most cunning artificer in metal work, and made all kinds of chalices, patens, bells, and shrines for the use of his churches and monasteries. It appears to be quite evident, too, that he founded a school of metal work and decorative art at Kildare, which was conducted with much success under his successors in that see. In our own times sacred art is left to take its chance; little or no official patronage is extended to the workmen, and no special care is given to their training. Not so in ancient Erin. The greatest attention was paid to these subjects, and, as we know, the arts of metallurgy, of the illumination of MSS., of sculpture, and of architectural ornamentation were carried to the greatest perfection under the patronage of distinguished ecclesiastics. The ancient buildings of Kildare have, with the exception of the Round Tower, completely disappeared. This is all the more to be regretted, when we see the beautiful ornamental door-way of the Round Tower, a class of buildings in which ornamentation of any kind is rarely met with. Even in the time of Giraldus Cambrensis it was a venerable building, and he tells a story of a falcon that used to nestle in its summit all alone, admitting no mate, and was on quite familiar terms with the monks and citizens, for it was called St. Brigid's bird. This beautiful tower, the tallest in Ireland, is 136 feet 7 inches in height, and still pointing heavenward, as of old, marks out for every stranger who travels by the Great Southern Line, the sacred city of St. Brigid, in the great plain of the Liffey.
