Antoine Philibert Albert Bailly (1 March 1605 - 3 April 1691) was a Savoyard clergyman who was bishop of Aosta from 1659 until his death.
Born in 1605 to Barthélémy Balli and Béatrix de Loziano,[1] he studied with the Jesuites of Chambéry and after he moved to Turin, where he became secretary of Victor Amadeus I, Duke of Savoy. He became a Barnabite priest in 1633.
He was ordained as a bishop in March 1659.
Although not a native of the Aosta Valley, Bailly remains, as a devoted defender of local freedoms, a cultural and historical figure of the valley. He is considered by Lin Colliard as "the best and the most prolific Valdôtain writer of the time" and Rosanna Gorris[2] stated that "the most important writer of Valdôtain 17th century literature is certainly Albert Bailly, bishop of Aosta".
