Thisbe in Greek and Roman Biography and Mythology
1. A beautiful maiden at Babylon, was beloved by Pyramus. The
lovers living in adjoining houses, often secretly conversed
with each other through an opening in the wall, as their
parents would not sanction their marriaqge. Once they agreed
upon a rendezvous at the tomb of Ninus. Thisbe arrived first,
and while she was waiting for Pyramus, she perceived a lioness
who had just torn to pieces an ox, and took to flight. While
running she lost her garment, which the lioness soiled with
blood. In the mean time Pyramus arrived, and finding her
garment covered with blood, he imagined that she had been
murdered, and made away with himself under a mulberry tree,
the fruit of which henceforth was as red as blood. Thisbe, who
afterwards found the body of her lover, likewise killed
herself. (Ov. Met. 4.55-165; comp. Anthol. Lat. i. p. 106, &c.
