Martin of Vienne explained

Saint Martin of Vienne was the legendary third bishop of Vienne, in France, believed to have lived in the 2nd (or 3rd^[1]) century. He is venerated as a saint by the Catholic Church and the Eastern Orthodox Church, with a feast day celebrated locally in Vienne on 1 July.

Although he is mentioned in the 8th century by Archbishop Ado in his Chronicles,^[2] it has since been questioned whether he ever existed.^{[3] [4]}

A district and a bridge in the old town of Vienne are named after him, as is the town of Saint-Martin-l'Ars, in the department of Vienne.^[5]
