After she [Thisbe] had perceived her own garment, and beheld, too, the ivory sheath without its sword, she said, "Tis thy own hand, and love, that has destroyed thee, ill-fated youth! I, too, have a hand bold enough for this one purpose; I have love as well; this shall give me strength for the wound. I will follow thee in thy death". . .Thus she said; and having fixed the point under the lower part of her breast, she fell upon the sword, which still was reeking with his blood.
[Ovid, Metamorphoses]
JULIET: "What's here? A cup, clos'd in my true love's hand?
Poison, I see, hath been his timeless end.
O churl! drunk all, and left no friendly drop
To help me after? I will kiss thy lips.
Haply some poison yet doth hang on them
To make me die with a restorative. [Kisses him.]
Thy lips are warm! [Snatches Romeo's dagger.]
This is thy sheath; there rest, and let me die. [She stabs herself and falls on Romeo's body.]
[Shakespeare, Romeo and Juliet]
