Mega-famous choreographer Martha Graham created a dance piece called Clytemnestra in 1958, which tells the whole bloody story from the queen's perspective.

The epigraph from Harry Potter and the Deathly Hollows is taken from The Libation Bears, the second play of Aeschylus' Oresteia. (Oooh, look at J.K. getting all literary.)

"Orestes" is the name of a song by the band A Perfect Circle. (It rocks!)

Check it out: you can get an Orestes app for your phone with the whole text of the play by Euripides.

Eugene O'Neill's Mourning Becomes Electra is inspired by the Oresteia and places similar events in post-Civil War Connecticut.

Orestes, Indiana, is named after a kid called Orestes McMahon who was born on Christmas Day in 1876. (Thankfully, he did not repeat the matricidal behavior of the original Orestes.)
