Note Of Cerberus and blackest Midnight born — MILTON’S MINOR POEMS.
Reading edition
2. Of Cerberus and blackest Midnight born. Milton follows the example of the ancient poets in announcing the parentage of the principal beings whom he brings upon his stage. Moreover, he uses the ancient freedom in assigning mythical pedigrees, not only adopting no authority as a canon, but allowing his own fancy to invent origins as suits his purpose. He knew the Greek and Latin poets, and assumed for himself the privilege which they exercised of shaping the myths as they pleased. We are not therefore to seek in Milton a reproduction of any system of mythology. Cerberus was the terrible three-headed dog of Pluto. His station was at the entrance to the lower world, or the Stygian cave.
