Before visiting his father, in what region did Phaethon live?

Phaethon, the son of Helios, the Sun god, is often associated with the region of Egypt in various mythological stories. In Greek mythology, Egypt is depicted as a land where various gods and mythical beings have significant interactions, and it was considered a place of great cosmic significance. Phaethon, being the son of Helios, represents the connection between divine light and earthly regions, with Egypt being one of the places where this duality is fully realized.

Egypt's status as an ancient civilization known for its sun worship and reverence for celestial deities aligns well with Phaethon’s narrative. This mythological backdrop enhances the understanding of Phaethon’s heritage and character, positioning him in a context closely tied to themes of light, the sun, and divine ancestry.

The other options, while they are all significant regions in ancient history, do not typically feature in the myths concerning Phaethon's origins, making Egypt the most fitting and contextually accurate choice for where Phaethon lived prior to his journey to visit his father.
