Zodiacs.

The first of the twelve Babylonian arcs, aligned in antiquity with the constellation later called Aries; the opening position gave it primacy in the Hellenistic ordering of the wheel.

Among the oldest constellation identifications in the sky, with bull imagery in the region predating the formal Babylonian zodiac by well over a millennium.

Recorded in Babylonian sources as the "Great Twins," carried directly into Greek Dioscuri imagery and the Ptolemaic wheel.

The crab constellation is one of the faintest in the zodiac band, yet its position marking the summer solstice point in antiquity secured its place in the record.

Identified with a lion figure across multiple ancient Near Eastern sky traditions before its formal absorption into the Babylonian and Hellenistic zodiac.

Consistently depicted as a maiden holding grain across Babylonian and Greek sources, and linked to the autumn harvest in the agricultural calendar.

The only inanimate-object sign; Roman sources formalized it as the scales, split off from what earlier Babylonian tradition had treated as Scorpio's claws.

One of the oldest constellation figures on record, with scorpion imagery tied to this region of sky in Mesopotamian sources well before the twelve-sign system was formalized.

Depicted as an archer, often centaur-form, in Babylonian boundary-stone art centuries before its Hellenistic codification into the zodiac proper.

The composite goat-fish figure appears on Babylonian boundary stones over three thousand years old, among the most persistent images in the zodiac's visual record.

Water-bearer imagery appears in Babylonian sources associated with the season of rains, later absorbed into the Hellenistic wheel under the same figure.

The last sign in the sequence; Hellenistic sources describe two fish tied together, a figure already present in earlier Babylonian sky tradition.
