Mars is a nocturnal malefic. Why? Well, why are 'daylight robberies' unusual? Because it's not expected. "The night is dark and full of terrors". Why are werewolves associated with the Moon, why do vampires hate the Sun? Darkness is dangerous, it's Mars's time of day. (thread)
Aspects have benefic/malefic qualities and diurnal/nocturnal associations. As a planet is in a waning sextile with the Sun, it becomes increasingly less visible. When it's in a waxing sextile with the Sun, it's moving toward visibility but it's still less visible. (cont)
