My friend John Perlin is a leading expert regarding ancient peoples' knowledge of solar principles. He recently alerted me to this passage in Shakespeare's The Life and Death of Julius Caesar (1695).
Perlin is impressed by Shakespeare's high awareness of solar geometry. Casca tells Decius Brutus, Cinna, and Cassius that the sun rises South-of-east (in Winter), but in the "youthful season" (Spring) it will rise North-of-east.
Perlin wrote the excellent Let It Shine: The 6,000-Year Story of Solar Energy (2013), which built upon and revised his landmark A Golden Thread: 2500 Years of Solar Architecture and Technology (1980).
