Peris was an early Christian monk from Wales, likely active during the 6th century. According to the Bonedd y Saint, he is identified as a Cardinal of Rome, though he may have been a son of Helig ap Glannog. He is associated with the secluded area of Nant Peris in North Wales, where he is thought to have lived in solitude. He serves as the patron saint of Llanberis.
Life and traditions
The saint is linked to several geographical features in North Wales, including a lake and the village of Llanberis. Local tradition mentions a well called Ffynnon Peris, where he reportedly drank every day and kept two fish. His servant, a soldier named Cian, later became a hermit in Caernarfonshire.
Veneration
Peris is commemorated in the Catholic Church on 11 December. His memory is preserved through a church in the village of Nant Peris dedicated to him. The name of the nearby village, Llanberis, as well as Llyn Peris, also derive from his name.
