PTOLEMY; Claudius; 120-180; greek

This heir of the greek philosopher believed in geocentrism, a system that was to last for 15 centuries until COPERNIC. He observed from Alexandrian between 127 and 141AD and wrote two books: "Megiste Syntaxis" (Almageste in arab) in 140 and "Geography". Ptolemy recorded the observation of 7 nebulae: 3 asterisms without interest, the two discoveries from HIPPARCHOS and two own discoveries: M7 and Mel 111.
