Map created in Guide 7.0 with the figure outline based on Johannes Hevelius' Uranographia (1690). Click on the object's name to access its image or click on the name of adjacent constellation to see its map.
Hydra represent the multiheaded serpent killed by Hercules. The association between those two constellations predates Hercules, however, and came from Mesopotamia. Slaying of a multiheaded snake by Ninurta, the god of war, was mentioned on a cuneiform tablet from 2400 B.C.
M83 is my favourite deep sky target in Hydra.
