The stamp displays the central panel of a mosaic found in the synagogue at Beth Alpha. The mosaic is dated, by an inscription on the mosaic floor, to the reign of Justinian (518-527 a.d.). The zodiac circle surrounds the chariot of the sun drawn by four horses. The zodiac is divided into four seasons. The original kept Scorpio and Libra together, and Virgo, Leo, Cancer and Gemini together. Each month has an astrological sign similar to those used today.
