Constantius of Lyon

Constantius of Lyon (fl. {{circa|AD 480}}) was a cleric from what is now the Auvergne in modern-day France, who wrote the Vita Germani, or Life of Germanus, a hagiography of Germanus of Auxerre. The hagiography was written some time during the second half of the fifth century, and was commissioned by Patiens, bishop of Lyon.{{cite web|last1=Garcia|first1=Michael|title=Saint Alban and the Cult of Saints in Late Antique Britain|url=https://www.academia.edu/3585748/Saint_Alban_and_the_Cult_of_Saints_in_Late_Antique_Britain|accessdate=19 November 2014}}
