Illtud
He founded the monastery and college in the 6th century, and the school is believed to be Britain's earliest centre of learning.[1] At its height, it had over a thousand pupils and schooled many of the great saints of the age, such as David, Samson of Dol, and the historian Gildas.[3] The earliest mention of Illtud is in the Vita Sancti Sampsonis, written in Dol, Brittany, about 600 AD.[6] Inspired, Illtud drove out[6] his wife, and became a hermit in the Vale of Glamorgan (a matrimonial detail which was regarded as dubious).[4] Illtud's own pupils are reckoned to have included seven sons of British princes and scholars such as Saint Patrick, Paul Aurelian, Taliesin, Gildas and Samson of Dol.[7][8][9] Saint Illtud's feast day and commemoration is celebrated on 6 November,[10][11] but the great 'pardon of Ildut' at Locildut in Brittany is held on the last Sunday of July.Near this church, there is a megalithic monument called Bedd Gwyl Illtyd, or the "Grave of St. Illtud's Eve."Until comparatively recently, Illtud was honoured by the practice of ‘watching’ (keeping vigil) at this stone before his festival.
