Galatea shows us the beautiful craft of Miller's stories once again, giving a voice to those history has forgotten, to those minimized, villainized and/or ostracized by old habits, beliefs and morals. 
Much like "Circe" this is a feminist retelling of a mythological tale. 
The original perspective, found in Ovid's Metamorphoses, is put aside as the perspective shifts to Galatea, the woman sculpted from ivory by Pygmalion.
In just a few pages Miller manages to give Galatea more personality and humanity than any God or Goddess could give. Through Miller's writing Galatea really comes to life, not just flesh, not just as Pygmalion's wife. As a woman, as a mother, as a symbol that every woman can relate to to some degree.
