Plutarch Quotes
We learn from Plutarch, that this was the theme of one of the hymns of Orpheus, so celebrated in the fabulous ages of Greece. It was brought by him from the banks of the Nile; and we even find in his verses, as in the Indian systems, a definite period assigned for the duration of each successive world. The returns of great catastrophes were determined by the period of the Annus Magnus, or great year, a cycle composed of the revolutions of the sun, moon, and planets, and terminating when these return together to the same sign whence they were supposed at some remote epoch to have set out. The duration of this great cycle was variously estimated. According to Orpheus, it was 120,000 years; according to others, 300,000 and by Cassander it was taken to be 300,000 years.
Charles Lyell
Like Plato and Plutarch, Xenophon was never tired of praising Spartan ways. Here it was, of course, that Plato found the outlines of his Utopia, a little blurred by a strange indifference to Ideas. Weary and fearful of the vulgarity and chaos of democracy, many Greek thinkers took refuge in an idolatry of Spartan order and law. They could afford to praise Sparta, since they did not have to live in it. They did not feel at close range the selfishness, coldness, and cruelty of the Spartan character; they could not see from the select gentlemen whom they met, or the heroes whom they commemorated from afar, that the Spartan code produced good soldiers and nothing more; that it made vigor of body a graceless brutality because it killed nearly all capacity for the things of the mind.
