The Dendera Zodiac is a circular bas-relief carved into the ceiling of the Osiris chapel on the roof of the Temple of Hathor, dating to the late Ptolemaic or early Roman period. It is the oldest known full representation of the classical Western zodiac in a circular form, combining Egyptian astronomical tradition with Greek iconography introduced after Alexander the Great's conquest of Egypt.
The zodiac depicts the constellations in a circular arrangement, including figures recognisable as Taurus, Leo, Scorpio, and other zodiac signs alongside Egyptian deities. Its astronomical accuracy and the precision of its astronomical alignments have been the subject of scholarly analysis for two centuries. What you see in the chapel today is a painted plaster cast; the original sandstone relief is displayed at the Louvre in Paris.
