The Constellations are patterns in the sky which have been to invented and have deep mythology behind them. Constellations cover massive areas in the sky and as such are very easy to find.

Sagitta is the third-smallest of all constellations (only Equuleus and Crux are smaller). Ptolemy included it in his list of 48 constellations. At that time, however, it was even smaller, spanning only about 4 sq. deg. It's also on the list of 88 constellations now acknowledged by the IAU.
Being located not very far to the north of the equator, this constellation can be seen from everywhere except for the southernmost part of the world.
Although Sagitta doesn't contain any bright stars, many cultures have seen an arrow in it , among them the Persians, Hebrews, Greeks and Romans. So there are various stories trying to explain the meaning of Sagitta. The two most important ones both take into account the neighbouring constellations Hercules, which had in earlier times been identified as a stag, (to the west) and Aquila (to the east).
Notable Objects in Sagitta
Messier 71 is a very loose globular cluster mistaken for quite some time for a dense open cluster.
