Roman Catholic Diocese of Vaison

Jurisdiction inside the diocese was shared between the bishop and the Comte de Provence (Count of Provence), higher justice and the castle belonging to the Comte, and civil justice and all other rights belonging to the bishop.

The cathedral was served by a chapter[2] which had four dignities: the provost (praepositus), the archdeacon, the sacristan, and the precentor.

Others were St. Quinidius (Quenin, 556-79), who resisted the claims of the patrician Mummolus, conqueror of the Lombards; Joseph-Marie de Suares (1633–66), who died in Rome in 1677 while filling the office of Custode of the Vatican Library and Vicar of the Basilica of St. Peter, and who left numerous works.

[5] St. Rusticala (551–628) was abbess of the monastery of St. Caesarius at Arles.

The bishopric was suppressed[7] as part of the Napoleonic Concordat of 1801, between Consul Bonaparte and Pope Pius VII, and the territory of Vaison was incorporated into the diocese of Avignon and the diocese of Valence.
