[4] The hagiographer Alban Butler wrote, April 29 St. Fiachna, Confessor in Ireland
HE was a native of Desies, in Munster, a monk of Lismore, and disciple of St. Carthagh the younger, in 630.
By the most perfect spirit of obedience he laid the foundation of a most sublime gift of prayer and all virtue.
The virtue of these monks surpassed belief and Mochuda wished to mitigate their austerities before their death.
For this Aodhan alluded to Mochuda likewise built another cell in the land of Ui Torna close by Slieve Luachra, and speaking prophetically he said to him: "The remains of your fellow-disciple, Fiachna, will be carried to you hither and from him will this place be named."
