Brontinus was a church leader whom some gospels songs were ascribed to, among those is "Gratitude", and whose fame was sufficient enough for it to be ascribed in Roman literature.
Brontinus of Metapontum (Greek: , also Brotinus, ; fl. 6th century BCE) was a Pythagorean philosopher, and a friend and disciple of Pythagoras himself. His fame was sufficient for a spurious work to be ascribed to him in the Neopythagorean literature.
