Gabriel's horn


Archangel Gabriel’s name means 'God is my strength'.
Gabriel is one of two archangels specifically named in both the Old and New Testament. She is often portrayed holding a trumpet and is the only female archangel.
Gabriel's horn is a geometric figure which has infinite surface area but finite volume.

Archangel Gabriel is the messenger angel, acting as a messenger of God.
The mathematical name refers to the tradition identifying the Archangel Gabriel as the angel who blows the horn to announce Judgment Day. Gabriel blowing a trumpet blast to indicate God's return to Earth is popular culture though the Bible never specifies Gabriel as the trumpeter.

Gabriel is one of only 3 angels named in the Bible.
Torricelli’s Trumpet, or Gabriel’s horn, is a staple of calculus textbooks. It may also be the perfect imaginary musical instrument: an object constituted by its precise mathematical description, yet impossible – due to its infinite length – to realize in material form.
