Athaloc was the Visigothic Arian Archbishop of Narbonne at the time of the Third Council of Toledo in 589.
Early in 589, Reccared I sent word of his conversion to Catholicism to Septimania, where it incited a rebellion on behalf of Arianism by two prominent counts, Granista and Wildigern, and the bishop Athaloc.
The rebels sought to overthrow Reccared and the Catholic faith and to this end they called in the aid of the Catholic and Frankish king of Burgundy, Guntram.
The Frankish army under Boso, however, was destroyed by Claudius, Duke of Lusitania.
