Page "Apollo" Paragraph 74

When Zeus ' wife Hera discovered that Leto was pregnant and that Zeus was the father, she banned Leto from giving birth on " terra firma ".

In her wanderings, Leto found the newly created floating island of Delos, which was neither mainland nor a real island.

She gave birth there and was accepted by the people, offering them her promise that her son would be always favourable toward the city.

Afterwards, Zeus secured Delos to the bottom of the ocean.

This island later became sacred to Apollo.
