The Ecliptic
The apparent path of the sun, tilted 23.4° to the celestial equator. Every planet keeps close to it — which is why the twelve houses form a band, not a scatter.

The Twelve
Twelve houses divide the ecliptic — the sun's slow road through the year. Hover a house to raise its constellation in the sky above; select it to hold the light.
The Reading
The sky was the first map, and the first story.
Long before there were coastlines on paper, there were figures in the dark — a ram, a pair of scales, a scorpion with a curled tail. People joined the brightest points with imagined lines and hung their calendar, their harvest, and their fate on the result. A constellation is not a thing in the sky. It is an act of reading.
We do not chart the stars. We chart the lines we choose to draw between them.
ZODIAC treats the night as an instrument. The twelve houses are not predictions but positions — coordinates for where you stand in a turning year. The wheel above rotates as the real sky does, one full turn against the frame, patient and indifferent. Hold a sign and the map leans toward it, the way a reader leans toward a familiar line.

Precession
Earth wobbles like a slowing top, one turn every 25,772 years. The pole star drifts; the signs slip against the seasons. No sky is fixed.

Sidereal Time
The clock the stars keep, four minutes faster than the sun each day. The readout above is the right ascension now crossing the meridian at Greenwich.
