Gabriel's Horn (also called Torricelli's trumpet) is a geometric figure which has infinite surface area, but finite volume. The name refers to the tradition identifying the Archangel Gabriel as the angel who blows the horn to announce Judgment Day, associating the divine, or infinite, with the finite. The properties of this figure were first studied by Italian physicist and mathematician Evangelista Torricelli.

“The rose and poppy are her flowers; for where
Is he not found, O Lilith, whom shed scent
And soft-shed kisses and soft sleep shall snare?
Lo! as that youth’s eyes burned at thine, so went
Thy spell through him, and left his straight neck bent
And round his heart one strangling golden hair.”
—Dante Gabriel Rossetti (1828–1882)
“The hounding of a dog pursuing a fox or other animal in the horizon may have first suggested the notes of the hunting-horn to alternate with and relieve the lungs of the dog. This natural bugle long resounded in the woods of the ancient world before the horn was invented.”
—Henry David Thoreau (1817–1862)
