Thisbe

From the name of an ancient Greek town in Boeotia, itself supposedly named after a nymph. In a Greek legend (the oldest surviving version appearing in Latin in Ovid's Metamorphoses) this is the name of a young woman from Babylon. Believing her to be dead, her lover Pyramus kills himself, after which she does the same to herself. The splashes of blood from their suicides is the reason mulberry fruit are red.
