The name Galatea is a girl's name of Greek origin meaning "she who is milk-white". Galatea and is often added to lists like Celestial Baby Names and discussed in our forums with posts like "Picky Parents BNG".
From the experts:
This name's meaning derives from the material from which the mythical sculptor Pygmalion chiselled his ideal woman - she was carved from ivory. Pygmalion fell in love with his creation and Aphrodite, taking pity on him, brought the sculpture to life. The woman was named Galatea due to her incredibly pale skin. The Pygmalion myth was the inspiration behind the story of "My Fair Lady" starring Julie Andrews on stage and Audrey Hepburn on screen.
