Of course, the history nerds amongst us will know that the internal organ that the Ancient Greeks associated with love was the spleen, not the heart - a fact used to great humorous effect in an episode of Lynne Truss's Radio 4 sitcom Acropolis Now (only on Radio 4 could you have a sitcom with a Greek chorus, parodying the conventions of Ancient Greek drama and namechecking obscure philosophers). As usual, my get-out clause for this apparent anachronism is that the Amazons aren't actually Greek, and so they're free to associate whatever organ they like with romantic feelings. Hur hur hur...
