Well, if it's an essay, you only need to write your opinion on Aphrodite, right?
I suggest you research a bit about her. I know she's the goddess of Beauty, Love and Lust, she was depicted as a beautiful woman usually accompanied by the winged godling Eros (Love). Her attributes included a dove, apple, scallop shell and mirror.
There's a lot more trivia to it. Good Luck! But I found a good source of info for it.
