Saint Sisebut de Cardeña

Saint Sisebut of Cardeña (died 1086 in Cardeña) was a Spanish Benedictine monk and abbot of the Monastery of San Pedro de Cardeña. He is venerated as a saint by the Catholic Church. According to the Cantar de mio Cid, El Cid left his wife and daughters under the protection of Abbot Sancho, and some critics have believed that the author of the Cantar was referring, in error, to Sisebut, although there are no compelling reasons to establish this identification between the Sancho of literary fiction and the historical Sisebut.
