 Similar town dedications were common in Roman Gaul, and toponyms often kept a Gallic element.When the location needed to be distinguished from other Juliomagi, it was known as Juliomagus Andecavorum ("Juliomagus of the Andecavi"), in reference to the principal Gallic tribe in and around the city.Around  400, the city came to be referred to as the civitas Andecavorum ("tribal capital of the Andecavi").
