This opinion is only one of several held by Catholic scholars. Dom Morin holds strongly, and gives very good reasons for his view, that it was written by Martin of Braga between the years 550 and 580. It was written, he says, for the people of Galicia in Spain, who had been recently converted from Arianism (Journal of Theological Studies, April, 1911). It was adopted into Gallican liturgy and office about 980, and in the Roman office only when the Curial Breviary was adopted.
“The liturgical use of the Athanasian Creed was Frankish in origin (ninth century) and spread through the influence of the Cluniac reform (tenth century), but only found its way to Rome in the Supplementary prayers in the twelfth and thirteenth century” (Burton and Myers, op. cit., p. 51).
