Aymon de Cossonay

from Wikipedia, the free encyclopedia

Aymon de Cossonay (* before 1317; † 4 March 1375 in Lausanne) was Bishop of Lausanne from 1355 to 1375.

Life

Aymon was descended from the noble family of de Cossonay in Vaud. He was the son of Jean II, Lord of Cossonay, and Marguerie de Villars. After the early death of his brother Louis I. († before 1333), he became the guardian of his children. From 1328 he was canon, and from 1346 vicar-general at Lausanne. Pope Innocent IV appointed him bishop of Lausanne in 1355. After the appointment of Count Amadeus VI of Savoy as imperial vicar, Aymon was forced to acquiesce in the appointment of an appellate judge in Lausanne by the Count of Savoy. On his journey to Avignon in 1365, Emperor Charles IV granted Aymon the imperial vicariate over the diocese of Lausanne and its neighbouring dioceses. With the Plaid général of 1368, he gave Lausanne’s customary law an official form.
