Maximus was the first Visigothic bishop of Zaragoza (Hispania) in 592–619.
He succeeded Simplicius of Zaragoza as Bishop and was influential in the conversion of the Visigothic Kings to Catholicism.
Maximus also contributed to the Visigothic cultural renaissance of the 6th and 7th centuries, which was continued by such scholars as Isidore of Seville, Eugenius of Toledo and Braulio of Zaragoza.
It has been theorized that he wrote the Chronicles of Zaragoza, a history of that time surviving via a 16th-century manuscript copy, because Isidore of Seville notes that Maximus had written on history.
However, Collins (1980) and Johnson (1993) argue that the Chronicles were not the work of a single author.
