Born into the Visigothic aristocracy around 630, he eventually abandoned a worldly life to seek spiritual solitude. He lived as a recluse near Astorga, where he faced various hardships and conflicts with local clergy. He is primarily recognized for his surviving literary works, which provide detailed accounts of his personal struggles and spiritual experiences.
