Hesychius II of Vienne

Saint Hesychius II of Vienne (Isicius) was metropolitan bishop of Vienne from about 545 until his death around 565. He is called the second to distinguish him from Hesychius I, father and predecessor of Saint Avitus. He is venerated as a saint in the Western Church.

According to the historian Bernard Bligny he came from one of the great Gallo-⁠Roman families of Burgundy, the Hesychii, a branch of the Syagrii, several of whose members were bishops at Vienne and Grenoble. His epitaph shows that he had been a quaestor before he was elected bishop, like his predecessor Pantagathus. He signed at the Fifth Council of Orléans in 549 and at the council of Paris around 552.

He was buried by his sister Marcellina near the tomb of Saint Avitus. His veneration appears in the calendar of Vienne in the 15th century and was confirmed by Pope Pius X in a decree of 9 December 1903. The Roman Martyrology remembers him on 12 November in the Western calendar, and on 1 July he is commemorated together with Saint Martin and all the saintly bishops of Vienne.
