Computer model of the Antikythera Mechanism’s display: in the center, the dome of the Earth, the phase of the Moon and its position in the Zodiac -- then rings for Mercury, Venus, true Sun, Mars, Jupiter, Saturn and Date, with ‘little sphere’ markers and smaller markers for oppositions. Scale marks and index letters for the synodic cycles of the planets are inscribed on the planet rings. Surrounding these, the Zodiac and the Egyptian Calendar. The true Sun ring has a ‘little golden sphere’ with ‘pointer.’ When the Moon and Sun pointers coincide, the Moon sphere shows black for New Moon; when the pointers are on opposite sides, the Moon sphere shows white for Full Moon. The Head of the Dragon Hand shows the ascending lunar node; the Tail the descending node. Small triangles on the true Sun ring, near the pointer, show wider and narrower eclipse limits. Eclipses are possible if the Dragon Hand is within these limits. When the Moon pointer is before the Head of the Dragon, the Moon is South of the node; after, it is North of the node -- conversely for the descending node. A Date pointer is attached to a narrow date ring, showing the date in the Egyptian Calendar. Image credit: Freeth et al., doi: 10.1038/s41598-021-84310-w.
