Caimin of Inis Cealtra

Saint Caimin of Inis Cealtra (Cammin) was a hermit and abbot on the island of Inis Cealtra (Inniskeltra) in Lough Derg in Ireland, who died in 653. Living first as a hermit on an island of the lake, he drew many disciples by his holiness. Then he founded a monastery and church on the island of the Seven Churches and worked together with Saint Senan. His monastery, a famous school, made the island a place of learning. A fragment of the Psalter of Saint Caimin, copied by his own hand, survives to this day. He is a saint of the undivided Church, commemorated on 24 March (new style; 6 April in the old style).
