Leo Palatinus

Leo Palatinus was a constellation created by the astronomer Karl-Joseph König in 1785. He created the constellation to honor the patrons, Count Palatine Charles Theodore and Countess Palatine Countess [Palatine Elisabeth Auguste of Sulzbach|Elizabeth Auguste], of the observatory in Mannheim, Germany, where he worked. However, the constellation failed to attract attention from contemporary and subsequent astronomers, and it was never depicted in a chart aside from the 1785 description.
Leo Palatinus was made of two non-contiguous groups of stars: a scattering of fourth-magnitude stars in far northwestern Aquarius made a crowned lion, and second part of even fainter stars west of Equuleus made a monogram CTEA above the lion.
