Final answer:
Leto gave birth to Apollo and Artemis on the floating island of Delos, according to Greek mythology.
Step-by-step explanation:
Leto, the mother of Apollo and Artemis, gave birth to her twins on the island of Delos. According to Greek mythology, Leto was a Titaness and daughter of the Titans Coeus and Phoebe. Hera, the wife of Zeus, was jealous of Leto and forbade her from giving birth on "terra-firma," or the mainland, as well as any island at sea. However, the floating island of Delos offered sanctuary to Leto, as it was not anchored to the ocean floor and therefore not considered a true island or part of the mainland. There, in the sacred surroundings, Leto bore the twin deities: Apollo, the god of music, healing, and the sun; and Artemis, the goddess of the hunt, wilderness, and the moon.
