Ava of Dinant

Saint Ava of Dinant (Avia), the holy nun, was a Benedictine abbess of the 9th century, venerated as a saint and patron of the blind. She was a niece of King Pepin (in some sources, of Pepin II of Aquitaine) and in childhood and youth was blind, but was miraculously healed by Saint Rainfredis (Renfroie).

After her healing she gave her fortune to the Church and became a Benedictine nun at Denain in Hainaut, in today's Belgium, and later abbess of her monastery. She reposed around 845. She is commemorated on 29 April, by the Western calendar (new style), as a saint of the undivided Church.
