The constellation of Sagitta is a tiny grouping of five fairly bright stars that form the outline of the "Arrow" this group is meant to represent. The constellation was introduced by the Greeks, but is so conspicuous that it is hard to see how it was not noted or used by other more ancient civilizations. It is said to represent one of the arrows Hercules used to kill the Stamphylian birds as part of his 12 labours, or alternatively, the arrow of cupid. Sagitta lies along the Milky Way between the rich constellations of Aquila and Vulpecula, and contains two beautiful star clusters and two very unusual stars that will interest the casual observer.
