The Egyptian town of Mallawi is not on the main tourist beat, given its location 260 miles and a seven-hour train ride north of the temple complexes at Luxor. But one of us (Symons) traveled there in May 2013 with Robert Cockcroft, a postdoctoral researcher in her laboratory, hoping to see one of the oldest astronomical records in the world. The record, which had been described only vaguely, was indeed there, but to their astonishment, it was not the only one.
