triangulum (trī-an´-gū-lum)—the Triangle. (face East.)
Location.—A line drawn from the star γ Pegasi to Algol in Perseus passes through β Trianguli.
The triangle is clearly defined and a beautiful figure. It lies just below Andromeda, and above Aries.
Triangulum is a very ancient constellation, being formerly named Deltoton, from the Greek letter Delta Δ.
It was in this locality that Piazzi discovered the asteroid Ceres, January 1, 1800.
α Trianguli is sometimes called "Caput Trianguli."
α and β Trianguli were known as "The Scale Beam." According to Argelander the constellation contains fifteen stars.
The Triangle has been likened to the Trinity, and the Mitre of St. Peter.
