Eimhin
Eimhin /ˈɛvᵻn/ was the abbot and bishop of Ros-mic-Truin (Ireland), probably in the sixth century.
Eimhin came from Munster, and was brother of two other saints, Culain and Dairmid. Of the early part of his religious life little is known.
Although the Abbey of Ros-mic-Truin was founded by St. Abban, it is said to have been colonized by St. Eimhin, and from the number of religious and students belonging to the south of Ireland who dwelt there the place came to be called "Ros-glas of the Munstermen". St. Eimhin is said by some to have been the author of the life of St. Patrick, called the Vita Tripartita (ed. Whitley Stokes in R.S.), originally published by the Franciscan John Colgan.
The date of Eimhin's death has not been recorded; however, competent authorities assign it to the earlier half of the sixth century.[1]
The feast-day of Saint Eimhin is observed in the Irish calendars on 22 December.
