Herodotus compares the Greek and the Persian systems of belief:

The erection of statues, temples and altars is not an accepted practice among them, and anyone who does such a thing is considered a fool, because presumably the Persian religion is anthropomorphic like the Greek. Zeus in their system is the whole circle of the heavens, and they sacrifice to him from the tops of mountains. They also worship the sun, moon, and earth, fire, water, and winds which are their only original deities: it was later that they learned from the Assyrians and Arabians the cult of Uranian Aphrodite. The Assyrian name for Aphrodite is Mylitta, the Arabian Alilat, the Persian Mitra.

Circe warns Odysseus about his adventure on the island of the Sun:

You will now come to the Thrinacian island, and here you will see many herds of cattle and flocks of sheep belonging to the sun-god -seven herds of cattle and seven flocks of sheep, with fifty head in each flock. They do not breed, nor do they become fewer in number, and they are tended by the goddesses Phaethusa and Lampetie, who are children of the sun god Hyperion by Neaera. Their mother when she had borne them and had done suckling them sent them to the Thrinacian island, which was a long way off, to live there and look after their father's flocks and herds. If you leave these flocks unharmed, and think of nothing but getting home, you may yet after much hardship reach Ithaca; but if you harm them, then I forewarn you of the destruction both of your ship and of your comrades; and even though you may yourself escape, you will return late, in bad plight, after losing all your men.
