This is a collection of moon lore: myths and folklore from all lands. The first part is mythological and mirthsome. It is the original nucleus around which the other parts have gathered. Some years since, the writer was led to investigate the world-wide myth of the Man in the Moon, in its legendary and ludicrous aspects; and one study being a stepping-stone to another, the ball was enlarged as it rolled. The second part, dealing with moon-worship, is designed to show that anthropomorphism and sexuality have been the principal factors in that idolatry which in all ages has paid homage to the hosts of heaven, as heaved above the aspiring worshipper. Man adores what he regards as higher than he. And if the moon is supposed to affect his tides, that body becomes his water-god.
