St. Gildas (516-570)
Gildas was an English noble who was taught by St. Illtyd. Later, as a teacher, he taught several saints himself. After he was ordained in Ireland, he returned to evangelize England, where he founded several churches and monasteries. He then became a hermit, living on the tiny island, where he wrote several works about holiness. He was one of Britain's earliest historians.

Reflections from the Saints

The rosary is said not with the lips alone, muttering Hail Marys one after the other. For a Christian vocal prayer must spring from the heart, so that while the rosary is said, the mind can enter into contemplation of each one of the mysteries.
– St. Josemaria Escriva
