Rare 2,000-year-old sundial uncovered from Roman excavation
A 2,000-year-old inscribed sundial has been uncovered by UK-based archaeologists during the excavation of a roofed theatre in an ancient Roman town. Carved out from a limestone block, the spherical sundial called 'hemicyclium' is engraved with 11 hour lines, marking 12 daylight hours, and three day curves indicating the seasons with respect to winter solstice, equinox, and summer solstice.
