Pyramus and Thisbe are the Greek equivalents to Romeo and Juliet. They are young and beautiful and very much in love with each other but their families, who live door to door, do not approve so their love is to be secret.
They are only able to glance and nod at each other when they see one another. One day they find a crack in the wall and through this wall, they whispers sweet words of love to each other. Sorry that they cannot kiss one another, they agree to take the chance and meet in the middle of the night outside of Babylon by old King Ninus’ grave.
Thisbe arrives to the rendezvous first. She is frightened by a lion and runs into a nearby cave. In her flight, Thisbe drops her veil by the spring. The lion finds it, plays with it and leaves it torn and bloody.
Pyramus finds the veil and thinks that his beloved has been killed. He stakes his sword and pierces himself while he cannot live without his love and would rather be united with her in death. The blood from his wound dyes the berries of the tree from white to red.
Thisbe hears the sound of Pyramus’ body falling to the ground. The maiden runs out and seeing him lying there, Thisbe tears out chunks of her golden hair and scratches her arms bloody. While Thisbe holds her dying beloved, she calls out to him: "It is I, Thisbe, who calls you my beloved!". Pyramus closes his eyes at this very moment and dies.
Thisbe cries out that their parents will let them rest side by side while she pierces herself with Pyramus’ bloody sword thus reuniting the lovers in death."
