Antinous, the youth:
The origins of this obsolete constellation date back to the year
132 and the Emperor Hadrian. He had this constellation placed in
the sky to honor a favorite youth of his court, who according to
myth sacrificed himself in order to prolong the life of the emperor.
Later astronomers recognized this constellation as the youth Ganymede,
who the Greek god Zeus had brought to Olympus by his eagle Aquila,
in order to serve as cup-bearer to the gods. The stars of this constellation
have since been given to the constellation of Aquila.
