(Abbreviation: Aql).
One of
the most distinctive of all the northern constellations, and of course, an
‘original’. Mythological it
represents an eagle, which was sent by Jupiter to collect a Phrygain shepherd
boy, Ganymede, who was destined to become cup-bearer of the gods – following an
unfortunate episode in which the former holder of the office, Hebe, tripped and
fell during a particularly solemn ceremony. The leading star is Altair. Altogether there are eight stars above
magnitude 4:
