From my studies of the Milky Way Mythology, I´ve found that crescent lunar symbols very often symbolizes the crescent shape of the Milky Way contours vaulting over the night Sky, depicting a great Serpent around the Earth in full figure and depicting a male figure on the northern hemisphere and a female figure on the southern hemisphere, thus describing the 3 main mythical figures of creation which is very directly connected to the Milky Way.
