Saint Beatus of Liébana (c. 730 c. 800) was a monk, theologian and geographer from the Kingdom of Asturias, in northern Spain, who worked and lived in the Picos de Europa mountains of the region of Liébana, in what is now Cantabria and his feast day is February 19. He created an important Christian cultural and religious focal point during the 8th century. He corresponded with Alcuin, and took part in the Adoptionist controversy, criticizing the views of Felix of Urgel and Elipandus of Toledo. As confessor to Adosinda, wife of Silo of Asturias, and as the master of Alcuin and Etherius of Osma, Beatus exercised wide influence. He is best remembered today as the author of the Commentary on the Apocalypse, written in 776, then revised in 784 and again in 786.
