Calendar of Scottish Saints – Saint Laserian or Molios, Abbot, A.D. 639


This saint was of princely race in Ireland. He seems to have been brought to Scotland at an early age, and to have been sent to Ireland for his education. Later on he returned to Scotland for a life of sanctity and solitude. A small island in the bay of Lamlash, off the coast of Arran, became his abode for many years. His virtues gave it the name it still bears of Holy Island.

Saint Laserian seems to have made a pilgrimage to Rome, where he was raised to the priest hood. Returning to Ireland, he afterwards became abbot of the monastery of Leighlin. He is said to have espoused with much zeal the Roman usage with regard to Easter.

In Holy Island, which was so long his solitary abode, are still to be seen traces of his residence. A cave scooped out of the rock bears his name, and a rocky ledge is called “Saint Molio’s Bed.” A spring of clear water near the cave is also pointed out as the saint’s well, and miraculous properties have been attributed to it. The cave itself is marked with many pilgrims crosses.
