Illtyd (also spelled Illtud and, in corrupt English, Eltut, and, in Latin, Hildutus) (died mid-6th century), was a Welsh saint, founder and abbot of Llanilltud Fawr (Llantwit Major) in the Welsh county of Glamorgan. He was also said to have re-established the attached monastery school known as Cor Tewdws, after it had been destroyed.
The 7th century 'Life of Saint Samson' claims that Illtyd was a disciple of Germanus of Auxerre (although this does not necessarily mean that he was taught by him directly), that he was the most learned Briton in the study of scripture and philosophy, and that he was the abbot of his monastery in Glamorgan. He appears to have been married at some stage and may have had a military background
In an age when any schooling was available only to a very few privileged people, perhaps Illtyd's monastic school of Cor Tewdws was the closest approximation in existence to an institution of higher education. Among Illtyd's pupils were Saints Pol Aurelian, Samson of Dol, Gildas and David, and the future King Maelgwn of Gwynedd.
Propers for Illtud of Llanilltud Fawr - 6 November - Teacher and Abbott
O God, whose blessed Son became poor that we through his poverty might be rich: Deliver us, we pray thee, from an inordinate love of this world, that, inspired by the devotion of thy servant Illtud, we may serve thee with singleness of heart, and attain to the riches of the age to come; through the same thy Son Jesus Christ our Lord, who liveth and reigneth with thee, in the unity of the Holy Spirit, one God, now and for ever. Amen.
