Medusa
(religion, spiritualism, and occult)Medusa, asteroid 149 (the 149th asteroid to be discovered, on September 21, 1875), is approximately 26 kilometers in diameter and has an orbital period of 3.2 years. Medusa was named after the famous Greek woman whose visage could turn men into stone. J. Lee Lehman associates this asteroid with “volcanic” temperaments, although she adds that in small doses, it may add spice to one’s character. Jacob Schwartz gives the astrological significance of Medusa as “the triumph of patriarchal forces over the matriarchal Gorgon Amazons of Lake Triton, or the slaying by Perseus, representing a naval triumph over the Gorgon rulers of the three main Azores islands, thus women of deadly abilities.”
