Ganymede
Aquarius is sometimes linked with Ganymede, a Trojan youth whom Zeus took to Mount Olympus to be cup-bearer to the gods.
Neighbouring Aquila is said to be the eagle that carried him off; one tradition, preserved in a scholium on Apollonius of Rhodes, credits Eos with the abduction.
Ea’s vase
Babylonian star catalogues name the constellation GU.LA, ‘the Great One’, an image of the god Ea holding an overflowing vase. Ea ruled the southernmost part of the Sun’s path, the ‘Way of Ea’, about 45 days either side of the winter solstice.
Linked with destructive floods, the constellation had a rather bad reputation.
The real constellation
Four stars, Gamma, Pi, Eta and Zeta, form the Water Jar. The Helix Nebula (NGC 7293), about 650 light years away, is the planetary nebula closest to Earth.
From Brussels, Sadalsuud climbs to 34 degrees and is highest around 10 pm in early October. In 2026 the Sun stood in front of Aquarius from 16 February to 12 March. This week the Moon passed through on Wednesday and Thursday evening.
