The God Beneath the Sea

Blurb

The God Beneath the Sea is a children's novel based on Greek mythology, written by Leon Garfield and Edward Blishen, illustrated by Charles Keeping, and published by Longman in 1970. It was awarded the annual Carnegie Medal and commended for the companion Greenaway Medal by the British Library Association. Pantheon Books published a U.S. edition with illustrations by Zevi Blum in 1971.
The novel begins with newborn Hephaestus cast from Mount Olympus by his mother Hera. He is raised in a grotto by Thetis and Eurynome and the two goddesses tell him various Greek creation myths. The novel continues with myths of the Olympians and the age of gods and mortals, and concludes with Hephaestus returning to Olympus, having been cast down for a second time after reproaching Zeus.
Garfield, Blishen, Keeping, and Longman collaborated on a sequel entitled The Golden Shadow. It is based on myths of the later heroic age, when divine activity was limited.
