Canes Venatici or the Hunting Dogs is a modern constellation, created by the Polish astronomer Johannes Hevelius 1611-1687 who introduced this constellation to the star maps in the 1680s. He introduced 9 new constellations of which 8 are surprisingly still used today.  Although most are faint groups that fit in-between the ancient classical constellations. Canes Venatici is probably one of the brighter examples.
