What are the motifs in Till We Have Faces by C. S. Lewis?

Male chauvinism is a recurring idea. There is no more "political correctness" in Till We Have Faces' Kingdom of Glome than anywhere in the real-life ancient world. Misogyny begins at the top, where the brutal King Trom is openly contemptuous of females. He ignores his two motherless daughters, assigning them to the care of slaves. They receive an education only, because the King wants his learned Greek slave, the Fox, to hone his teaching skills for the day when the King will have a son for him to tutor. The Fox brings from his native Greece a typical male chauvinism that is offended by women walking about Glome with faces uncovered, but as a slave, the Fox must remain silent.
