Emilian of Cogolla was a 6th-century Iberian saint and abbot who lived during the Visigothic period. Born in Berceo, he initially worked as a shepherd before dedicating his life to religious service following a spiritual experience. After studying under a hermit in San Felices, he served as a parish priest, though his frequent distribution of alms caused friction with other clergy. He eventually returned to a life of solitude, where he gathered a community of followers before passing away in San Millán de la Cogolla.
