Ancient Egyptian Calendar Reveals Earliest Record of 'Demon Star'
Ancient Egyptians may have chronicled the flickering of a star known as "the Demon," perhaps the earliest known record of a variable star, astronomers suggest.
The ancient Egyptians wrote calendars that marked lucky and unlucky days. These predictions were based onastronomical and mythological events thought of as influential for everyday life. The best preserved of these calendars is the Cairo Calendar, a papyrus document dating between 1163 and 1271 B.C.
