St Columban, Abbot of Luxeuil (615)

Born in Ireland around 540, he joined the great monastic movement that flowered in Ireland following the missionary work of St Patrick and his disciples. After spending some years in Irish monasteries, he made pilgrimage to Gaul with twelve other monks, planning to preach the Gospel wherever they were led. The king of Burgundy, learning of their holiness, gave them land, where in time three large monasteries were founded with St Columban as their spiritual Father. Here the Saint established the rule that became normal for many monasteries in the West: in addition to its severe penitential disciplines, it included provision for some monks to be in prayer at every hour of the day and night — laus perennis (unceasing praise), as it was called. (This practice was also adopted by the Monastery of the Unsleeping Ones (Akoimetoi) in Constantinople).
