Saint Edern was a ninth-century monk originally from Ireland who later became a prominent figure in Brittany. After spending time in Welsh hermitages, he moved to the Breton region to evangelize local areas like Plouédern. Accompanied by his sister, Jenovefa, he established a residence in a high summit area, which eventually gave its name to the locality of Edern. He is remembered as a holy man whose life and miracles left a lasting mark on the Finistère region.
Life and legends

Traditional accounts describe several miracles attributed to the monk. One legend tells of a stag that sought refuge under his monastic robe to escape hunters, becoming his lifelong companion. Another story recounts how he restored a cow to life after it was attacked by a local lord's dogs. He is also said to have healed a duke of Brittany, who subsequently built a church in Plouedern to honor him.
Veneration

The saint is commemorated on August 26 in both Catholic and Orthodox traditions. He is often depicted in art riding a deer, a symbol derived from the legend of the stag. Historically, he was invoked under the name Sancti Egidii, particularly by those seeking relief from ailments affecting the eyes.
