The brightest star, γ Sagittae, forms the top. In the north it borders on the constellationVulpecula, in the east onDelphinus, in the south on the Eagle and in the west on Hercules.
There are several versions of the mythological origin of the Arrow as a constellation.
First, it says that the constellation represents the arrow that killed the physician Asclepius. TheCentaurusCheiron had trained the son of Apollo to be an excellent doctor. Through studies of asnake, he discovered a way to bring the dead back to life. This displeased the God of the underworld, Hades, who asked his brother Zeus to end the life of Asclepius. Zeus granted Hades this request and had the doctor killed by an arrow from another centaur. To appease Apollo, he put Asklepios asOphiuchuswith the Serpent into the sky.
Another version is associated withHercules. Prometheus, who was punished by the Gods for the transmission of the fire to the people and thus chained to a rock, suffered infernal pain: Every day anEaglecame and ate from his liver. Because of his immortality, Prometheus could not escape the agony until Hercules killed the eagle with an arrow and released Prometheus.
In Roman antiquity, the arrow was later interpreted as the love arrow of Cupid, who initiated the passion of Zeus to the youngAquariusGanymede.
