English-speaking readers have a wide selection of studies to choose from, by such scholars as Sir Flinders Petrie, Ahmed Fakhry and I.E.S. Edwards. Scholarly volumes on the pyramids are available in French (notably, Jean-Phillipe Lauer’s Les Mystères des Pyramides [1974]), German (Rainer Stadelmann’s Die aegyptischen Pyramiden [1985]) and other languages. And there is no end to the popular tomes by non-Egyptologists, ranging from the flawed but interesting Riddle of the Pyramids (1974), by Kurt Mendelssohn, to the merely flawed Orion Mysteries (1994), by Robert Bauval and Adrian Gilbert.
