Aphrodite and Eros
To escape the monster Typhon, Aphrodite and Eros leapt into the Euphrates and turned into fish: that is Hyginus’s version, citing Diognetus of Erythrae.
In Ovid’s Fasti, Venus and Cupid are carried away on the backs of two fish. Hyginus also preserves another tale, in which fish are rewarded for helping an egg reach the shore.
The cord and the vernal point
Pisces grew out of a combination of Babylonian constellations, ‘the Great Swallow’ and Anunitum, ‘Lady of the Heavens’. In the astronomical diaries of the 1st millennium BC, part of it was called DU.NU.NU, ‘the fish cord’.
The March equinox now lies in Pisces, just south of Omega Piscium, and is slowly drifting towards Aquarius.
The real constellation
It is a faint constellation: its brightest stars go no further than magnitude 3.6. It holds van Maanen’s Star, the closest known solitary white dwarf, invisible to the naked eye.
From Brussels, Alpherg climbs to 54 degrees and is highest around 10 pm in late November. In 2026 the Sun stood in front of Pisces from 12 March to 19 April. This week the Moon passes through on Friday, Saturday and Sunday.
