The lucky numbers for a Capricorn shift every day, but 8 and 10 are common, according to many astrologists. Saturn is the ruling body of Capricorn, and the number 8 is associated with Saturn by several numerologists. Furthermore, Capricorn is the 10th house in astrology.
The symbol for Capricorn, a goat, is associated with several mythological stories. In one story, Zeus was hidden in a cave as a baby and drank the milk of this famous goat. This deception was to help avoid attention by Cronus, Zeus' father, who feared that one day his child would destroy his complete dominion of the Earth. Another story depicts the Capricorn symbol as a Babylonian goat-fish combination. Capricorn also has several ties to the concept of Pan, who was a mythological trouble maker.
