Mythology and History

Sagitta is the arrow with which Heracles hit the eagle who pecked at the liver of Prometheus every day, as punishment for stealing the fire from heaven for the people. According to another representation, the arrow is supposed to be the symbol of cosmic light.

The Greeks called the constellation Tóxon or Oistos, the Romans Latinized it to Sagitta and the Arabs spoke of El Sham . [10, 21]
