Paterius (died 606) was a bishop of Brescia. He is known as a compiler, in particular of works of Pope Gregory I, for whom he had worked as a notary.
His sole surviving work is the Liber testimoniorum veteris testamenti,[1] an anthology of Gregory's works of biblical exegesis, arranged in the order of the biblical passages discussed. The work survives in over 120 complete or partial manuscripts.[2]
