Saint Herve, sometimes called Harvey or Hervues, is venerated throughout Brittany but we have few reliable particulars on him--his life was not written until the late medieval period. All we really know is that he was a hermit in Brittany, where he is still highly venerated.
Herve was the son of the bard Hyvarnion, and was born blind. His father died when Herve was an infant. He was raised by his uncles because his mother became an anchoress.
He lived for a while as a hermit and bard, and then joined a monastic school at Plouvien which had been founded by his uncle. Abbot of Plouvien, he built an abbey at Lanhourneau.
He was venerated as a miracle worker and bard. He is reported to have a special ministry of healing animals, and to have a domesticated wolf as a companion.
He is invoked against eye trouble, and he is depicted with a wolf.
