Pallas

The goddess Pallas or Athena Pallas. Mentioned by Shakespeare in Sonnet 38, "the tenth muse. (Zeus had nine different muses and Pallas sprang directly from Zeus, rather than being his child. So.) She was Shakespaere's muse, his inspiration, the goddess of music and poetry, warrior against ignorance. Her name Pallas meaning "Spear Shaker" Sir Francis Bacon wrote of her as the Spear Shaker (as mentioned by John Barcia Argens 1634.. She is said to be the inventor of musical intruments. Her statue adorns many Greek temples, always with a helmet and golden tipped spear.
   Sir Bacon is credited with using Pallas as a source of inspriaration to his secret society of the 'Rosicrosse' (not rose cross but cross of the rose). This fraternity tied in with the secret society of the Masons (quoted from Alfred Dodd's 'The Martydom of Francis Bacon'.
