Crux (IPA: , ), commonly known as the Southern Cross (Crux Australis, in contrast to the Northern Cross), is the smallest of the 88 modern constellations, but nevertheless one of the most distinctive. It is surrounded on three sides by the constellation Centaurus while to the south lies the Fly (Musca). Ancient Greeks originally thought Crux was part of Centaurus, but it was defined as a separate asterism in the 16th century after Amerigo Vespucci's expedition to South America in 1501. Vespucci mapped the two stars, Alpha Centauri and Beta Centauri as well as the stars of the Crux. Although these stars were known to the ancient Greeks, gradual precession of the equinoxes had lowered them below the European skyline so that they were forgotten there. For example at the latitude of Athens in 1000 B.C., Crux was clearly visible, although it was low in the sky. However, by 400 A.D., most of the constellation never rose above the horizon for Athenians.
