12155 Hyginus           Discovered 1971 Mar. 26 by C. J. van Houten and I. van Houten-Groeneveld on Palomar Schmidt plates taken by T. Gehrels.
Gaius Julius Hyginus (c. 64 B.C.-A.D. 17), Roman historian, philologer and mythographer, presided over the Palatine Library in Rome. His De Astronomia (or Poeticon Astronomicon) gives a comprehensive overview of the myths associated with the constellations. The name was suggested by R. H. van Gent.
