Clytemnestra, wife of the infamous Agamemnon, Achaean King of Kings, was not only a superb manager of estate who remained in power while her husband was away in Troy, she is also an avenger and a regicide. Her character was confusing even to the ancients who spoke of her in plays and in plain gossip. It is worth noting that transgender here does not mean ‘dressing like the opposite sex,’ but rather taking on the ‘traits of the opposite sex’ as seen by the Ancient Greeks. Especially in Athens, the issue of who was a man and who a woman was quite huge in the 5th and 4th centuries.
Euripides, who has been classified as both a misogynist and a feminist by various scholars, writes at-length about these issues. One of his plays is precisely about Clytemnestra and her murder of Agamemnon. Aeschylus, Aristophanes and Sophocles all wrote about the Achaean Queen, bringing us a perspective quite different from what we think transgender roles are.
