She was once a beautiful woman, but she offended Athena, who changed her hair into snakes and made her face so hideous that all who looked at her were turned to stone. When Medusa was with child by Poseidon, Perseus killed her and presented her head to Athena. Chrysaor and Pegasus sprang from her blood when she died. Medusa's head retained its petrifying power even after her death. Because of this power, her image frequently appeared on Greek armor. In some myths Athena used the Medusa head on her aegis.MedusaIn Greek mythology, the mortal one of the three Gorgons, who had snakes for hair and whose head was cut off by Perseus to present to Athena as an ornament for her shield. 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.” Sources:Kowal, Charles T.
