Delphinus and Related Constellations in Classical Sky Maps
The Dolphin Delphinus is a small Greek-listed constellation with four bright stars forming a tiny kite shape and a dim companion group. It lies near the Little Horse and Sagitta, with Alpha and Beta Delphini nicknamed Sualocin and Rotanev after Nikolaus Venator spelled backward. The Little Horse sits southeast of the Dolphin, while Sagitta lies northwest opposite it. In myth, the Delphin is the creature that rescued the musician Arion from the ocean.
