It’s all Greek to me! Except for the parts that are Roman.

1. What fluvial English idiom refers to the same event as, but is not a translation of, the Latin “Alea iacta est”?
2. Name both of the prominent Greeks represented in the Rembrandt painting seen below.
3. The name Lesbia is not, as you might expect, associated with the Greek Sappho but with what Roman poet of neoteric verse who used it as a pseudonym for his lover Clodia?
4. Polynices, Amphiaraus, Parthenopeus, and four other captains are the leaders of the forces assailing what city in a play by Aeschylus?
5. The geometric objects depicted below are named for what thinker who discussed them in his work Timaeus?
