Roman Lyon

Irenaeus ( or ; ; ) was a Greek bishop noted for his role in guiding and expanding Christian communities in the southern regions of present-day France and, more widely, for the development of Christian theology by opposing Gnostic interpretations of Christian Scripture and defending orthodoxy. Originating from Smyrna, he had seen and heard the preaching of Polycarp, who in turn was said to have heard John the Evangelist.

Lugdunum (also spelled Lugudunum, ; modern Lyon, France) was an important Roman city in Gaul, established on the current site of Lyon.
