The Constellation Pisces: Two Fish, One Cord, and Today's Equinox Point

Pisces draws two fish tied together by a cord so they cannot drift apart, and somewhere inside this faint, unremarkable shape sits the single most consequential point in the whole tropical zodiac: the March equinox, still called the First Point of Aries two thousand years after it left the stars of Aries behind. This closes a twelve-part series on the constellations behind the zodiac signs, following the water bearer before it, and it ends exactly where the ram that opened the series actually stands today.

Aphrodite, Eros, and a knot that had to hold

Greek myth ties Pisces to the same ambush that sent Pan diving into a river to become Capricornus: Typhon, the monster bred to overthrow the gods, caught Aphrodite and her son Eros by a riverbank. They leapt into the water and transformed into fish to escape, and, wary of losing each other in the current, bound their tails together with a cord before swimming off. The knot survived into the constellation itself: the two fish sit at opposite ends of a wide V, joined at a star named Alrescha, Arabic for the cord, exactly where the ribbon connecting them was drawn to meet.

The fish outlasted the goddess who supposedly became one of them. A Syrian fish-tailed deity, Atargatis, held sacred status in the region for centuries before Greek myth ever reached it, and the two fish likely carried religious weight long before Aphrodite's name was attached to the story at all.

Why is Pisces so hard to pick out?

Because nothing in it is bright. Its most prominent star, Eta Piscium, barely reaches magnitude 3.6, and the rest of the constellation fades from there, a faint, sprawling zigzag that rewards a genuinely dark sky more than a quick glance upward. Pisces earns its importance from position, not brightness, the same way Aries does at the start of this series.

The equinox point is sitting here right now

Two thousand years ago, Hellenistic astronomers fixed the March equinox at the start of the sign Aries, and at that moment the equinox genuinely sat in front of the constellation Aries. It has not stayed there. The same slow axial wobble that separates the tropical and sidereal zodiacs has spent the centuries since sliding that point backward through the stars, out of Aries entirely and into Pisces, where it sits today, still carrying the old name First Point of Aries despite pointing at two tied fish instead of a ram. The drift continues at its usual pace, about one degree every 72 years, and the same arithmetic that walked the point out of Aries and into Pisces is already carrying it onward toward Aquarius.

Twelve signs, one thread running under all of them

Every entry in this series has circled back to the same fact from a different constellation: the zodiac sign and the constellation behind it agree in name only, pulled apart by a slow wobble in Earth's axis that neither the ram nor the twins nor these two tied fish had any say in. Pisces just happens to be where the reminder currently lives.
