As for your deriving religion from the sky and stars, do you not see what a long way this takes you? You say that the sun and moon are deities, and the Greeks identify the former with Apollo and the latter with Diana. But if the Moon is a goddess, then Lucifer also and the rest of the planets will have to be counted gods; and if so, then the fixed stars as well. But why should not the glorious Rainbow be included among the gods ? it is beautiful enough, and its marvelous loveliness has given rise to the legend that Iris is the daughter of Thaumas.
And if the rainbow is a divinity, what will you do about the clouds? The rainbow itself is caused by some coloration of the clouds ; and also a cloud is fabled to have given birth to the Centaurs. But if you enroll the clouds among the gods, you will undoubtedly have to enroll the seasons, which have been deified in the national ritual of Rome. If so, then rain and tempest, storm and whirlwind must be deemed divine.
