Miliau was a Breton saint and prince who lived during the late fifth or early sixth century. As the son of King Budic, he eventually held the chiefdom of Léon. Known for his justice and generosity, he was a protector of the poor, often depicted sharing his cloak with those in need. According to local legend, his reign was marked by a period of seven years where the land remained fertile despite a lack of rain or snow. He was eventually assassinated by his brother, Rivod.
