Urania's Mirror, Vintage Astronomy Celestial Map Key Ring

Vintage illustration astronomy and antique celestial image featuring three constellations, Gloria Federici, Andromeda and Triangula. Gloria Frederica was a constellation created by Johann Bode in 1787 to honor Frederick the Great, the king of Prussia who had died in the previous year. It was located in a region between the constellations Cepheus, Andromeda, Cassiopeia and Cygnus. It is no longer in use. Andromeda is a constellation in the northern sky named after Andromeda, the princess in the Greek legend of Perseus who was chained to a rock to be eaten by sea monster Cetus. It is sometimes called "the Chained Lady" or "the Chained Woman". It has also been called Persea (Perseus's wife) or Cepheis (Cepheus's daughter). The Andromeda Galaxy is named after the constellation, as it appears within its boundaries. Triangulum (Latin for triangle) is a small constellation in the northern sky. Its name derives from its three brightest stars, of third and fourth magnitude, which form a nearly-isosceles long and narrow triangle. Triangulum was one of the 48 constellations listed by the 2nd century astronomer Ptolemy, and remains one of the 88 modern constellations.
