Star Tales - Centaurus (ianridpath.com)
Centaurs were mythical beasts, half-man, half-horse. They were a wild and ill-behaved race, particularly when the wine bottle was opened. But one centaur, Chiron, stood out from the rest as being wise and scholarly, and he is the one who is represented by the constellation Centaurus (Κένταυσος in Greek).Star Tales - Musca (ianridpath.com)
A small constellation to the south of Crux, the Southern Cross. Musca was one of the 12 southern constellations introduced at the end of the 16th century by Pieter Dirkszoon Keyser and Frederick de Houtman from the stars they observed during the first Dutch expeditions to the East Indies. The constellation arose because the seafarers saw chameleons eating flies during their stopover on Madagascar, and in the sky the fly lies next to the constellation Chamaeleon. These new southern constellations were first depicted by their fellow Dutchman Petrus Plancius on his globe of 1598, but for some reason he left the fly unnamed. In de Houtman’s catalogue of 1603, completed after Keyser’s death, it is called De Vlieghe, Dutch for fly.- The smallest of all the 88 constellations. Its stars were known to the ancient Greeks, and were catalogued by Ptolemy in the Almagest, but at that time were regarded as part of the hind legs of Centaurus, the centaur, rather than as a separate constellation. They subsequently became lost from view to Europeans because of the effect of precession, which causes a gradual drift in the position of the celestial pole against the stars, and were rediscovered during the 16th century by seafarers venturing south.
