When and where was the Athanasian Creed probably composed?

The Athanasian Creed was likely composed in southern France during the 5th century. While scholars have proposed various authors, no definitive conclusion has been reached. However, the discovery of the lost Excerpts by Vincent of Lerins, which contains much of the creed's language, suggests he or an admirer may have been the author. The earliest known copy of the creed appears in a collection of homilies by Caesarius of Arles, who died in 542.123
