and the founder and patron saint of the city of Glasgow. Due to anti-Christian sentiment, he re-located for a time to Wales, where he established a monastery at St. Asaph's. Here he divided the monks into three groups. The unlettered was assigned to the duty of agriculture, the care of cattle, and the other necessary duties outside the monastery. He assigned 300 to duties within the cloister of the monastery, such as , preparing food, and building workshops. The remaining monks, who were lettered, he appointed to the celebration of divine service in church by day and by night. Wales Cadoc founded Llancarfan in the latter part of the fifth century. He received the religious habit from an Irish monk, St. Tathai, superior of a small community near Chepstow, in Monmouthshire. Returning to his native county, Cadoc built a church, and monastery, which was called Llancarfan, or the "Church of the Stags". There he also established a college and a hospital. His legend recounts that he daily fed a hundred clergy and a hundred soldiers, a hundred workmen, a hundred poor men, and the same number of widows. When thousands left the world and became monks, they very often did so as clansmen, dutifully following the example of their chief. Bishoprics, canonries, and parochial benefices passed from one to another member of the same family, and frequently from father to son. Their tribal character is a feature which Irish and Welsh monasteries had in common. Illtyd spent the first part of his religious life as a disciple of Cadoc at Llancarfan. He founded the monastery at Llanilltyd Fawr. One of his students was Paul Aurelian, a key figure in Cornish monasticism. Gildas the Wise was also a student at Llanilltyd Fawr, as was Samson of Dol. Samson founded a monastery in an abandoned Roman fort near the river Severn and lived for a time the life of a hermit in a nearby cave before going to Brittany. St David established his monastery on a promontory on the western sea, well placed to be a centre of Insular Christianity. His establishment became known for its austerity and holiness, more than as a centre of learning, although when King Alfred sought a scholar for his court, he summoned Asser of St David's. Contemporary with David were Teilo, Cadoc, Padarn, Beuno and Tysilio among them. Cornwall Many early medieval settlements in the region
