Pythagoras, according to Plutarch, located the Elysian Fields on the side of the Moon turned perpetually towards Heaven, never visible to the human eyes, and this is where the Caesars and the heroes went after death. Indeed, Pythagoras himself was thought by some to be a spirit descended from the Moon. Epiphnius writes that 'the disc of the Moon is filled with souls', while Roman senators, according to Kastor of Rhodes, would wear shoes dedicated with ivory crescents (lunules), to indicate that they would inhabit the Moon after they died."
Archaeologists Tony Sprawforth and Aubrey Burl suggested that aligning the stone with the Moon may have been a way to harness its powers of rebirth, as though the remains were were strategically positioned to enable the Moon, at the limit of its trajectory, to sweep up the souls of the dead and take them with it to their final resting place in the Moon.
This suggestion gains credibility from early practices in other parts of the world. For instance, when the Bushmen saw a hollow Moon which was lying down , they understood it to be carrying the dead away. In 1875, a Bushmen told Dr. Bleek what his parents had told him and what he had observed himself - that when people died the wind blew away their footsteps, their hair became clouds and their gall sat green in the sky:
... Mother was wont to do thus when the moonlying down came; (when) the moon stood hollow. Mother spoke, she said: 'The moon is carrying people who are dead... it lies hollow, because it is killing itself (by) carrying people who are dead. This is why it lies hollow... for it is a moon of badness... "
