Cogitosus, a monk of Kildare in the eighth century, expounded the metrical life of St. Brigid, and versified it in good Latin. This is what is known as the "Second Life", and is an excellent example of Irish scholarship in the mid-eighth century. Perhaps the most interesting feature of Cogitosus's work is the description of the Cathedral of Kildare in his day: "Solo spatioso et in altum minaci proceritate porruta ac decorata pictis tabulis, tria intrinsecus habens oratoria ampla, et divisa parietibus tabulatis". (The rood-screen was formed of wooden boards, lavishly decorated, and with beautifully decorated curtains. )
Probably the famous Round Tower of Kildare dates from the sixth century. Although St. Brigid was "veiled" or received by St. Macaille, at Croghan, yet, it is tolerably certain that she was professed by St. Mel of Ardagh, who also conferred on her abbatial powers. From Ardagh St. Macaille and St. Brigid followed St. Mel into the country of Teffia in Meath, including portions of Westmeath and Longford. This occurred about the year 468. St. Brigid's small oratory at Cill-Dara became the centre of religion and learning, and developed into a cathedral city. She founded two monastic institutions, one for men, and the other for women, and appointed St. Conleth as spiritual pastor of them. It has been frequently stated that she gave canonical jurisdiction to St. Conleth, Bishop of Kildare, but, as Archbishop Healy points out, she simply "selected the person to whom the Church gave this jurisdiction", and her biographer tells us distinctly that she chose St. Conleth "to govern the church along with herself".
Christus in nostra insula Que vocatur Hivernia Ostensus est hominibus Maximis mirabilibus Que perfecit per felicem Celestis vite virginem Precellentem pro merito Magno in numdi circulo.
(In our island of Hibernia Christ was made known to man by the very great miracles which he performed through the happy virgin of celestial life, famous for her merits through the whole world.)
The sixth Life of the saint printed by Colgan is attributed to Coelan, an Irish monk of the eighth century, and it derives a peculiar importance from the fact that it is prefaced by a foreword from the pen of St. Donatus, also an Irish monk, who became Bishop of Fiesole in 824. St. Donatus refers to previous lives by St. Ultan and St. Aileran. When dying, St. Brigid was attended by St. Ninnidh, who was ever afterwards known as "Ninnidh of the Clean Hand" because he had his right hand encased with a metal covering to prevent its ever being defiled, after being he medium of administering the viaticum to Ireland's Patroness.
