Lunar Eclipse diagram from Abu Rayhan al-Biruni, dating to 1019 AD. The Wiki translation of the writing reads: Why – why the increase and decrease of the light of the moon is settled while other stars don't behave so, observing these and not understanding the spirit of these is a misdeed that the light of the stars is of their own
Found this while thumbing through Scott Christianson's 100 Diagrams That Changed the World
