📖 - Parmenides — On Nature - Fragment 10

And you shall know both the nature of the aether and all
The signs in the aether, the destructive works
Of the splendid sun's pure torch, and whence they came-to-be,
And you shall learn the wandering works
Of the round-eyed moon, and its nature,
And you shall also know the surrounding sky,
Whence it grew and how Necessity did guide and shackle it
To hold the limits of the stars.
