What metaphors are used in Eros the Bittersweet by Anne Carson?

Carson notes that Bellerophon is a living metaphor for the space element of Eros, where Anteia desires him and Proitos wants to destroy him, a man who is deeply beautiful.

"Bellerophon is a living metaphor for the blind point of Eros, carrying on his face (beauty) and in his hands (tablet) a meaning he does not decode."
