History and mythology
This constellation belongs to the classical ones of the ancient times. Due to the similarity with the letter Δ (delta), the Greeks called it Deltoton. As it also represents the first letter of the greek name of Zeus, which is Dios, this constellation shall show the beginning of the cosmic order. So it is right by Aries which is the beginning of the zodiac.[1] Aratos of Soli compared it in his Phainomena with the island of Sicily: "Near the Andromeda the island of Sicily is located, which looks like a triangle whose shortest side is graced by two near stars." [2] Due to its form, Sicily was called Trinacia and was sanctified to Demeter. Also Persephone was kidnapped here and brought into Hades.[3]
