Antigone is not a Greek goddess, she's a character from a tragedy by Sophocles. Her mother is also her grandmother, and her father is also her half-brother, and she falls in love with her cousin. She later kills herself, and then her cousin/lover finds her body and kills himself and it's all quite incestuous and deranged and... just... don't name your mare Antigone. XD
I vote for Ellie, though :)
The hills were bathed in moonlight, the shadows not so stark;
Silver light reflected off his brown hide as he held me in the dark
– I love you, Mudpie!
