Viridiana was a 13th-century Italian anchorite born into the noble Attavanti family in Castelfiorentino. After undertaking significant religious journeys to Rome and Santiago de Compostela, she chose a life of seclusion. For thirty-four years, she lived as an anchoress, possibly as a member of the Franciscan Third Order, in connection with the Vallumbrosan abbey. She died in her birthplace on 1 February 1242 and was later canonized by Pope Clement VII.
