Italian researchers have claimed that they may have found signs of a second Sphinx beneath the Pyramids of Giza, suggesting a subterranean citadel. Radar engineer Filippo Biondi made the discovery during a recent episode of the “Matt Beall Limitless” podcast. He and his team were tipped off to the alleged underground guardian by explaining that lines between the pyramids to the known Sphinx also point to a parallel mound under which the second feline facsimile supposedly resides. Satellite images have reportedly captured this dune, which he claims measures approximately 108 feet tall. BionDi also noted that the Sphinx was carved with a pair of mythical cats, suggesting there were always supposed to be a second sculpture. Egyptologist Bassam El Shammaa first raised the theory more than a decade ago, citing ancient Egyptian records and mythology that describe a lightning bolt striking the Sphigil.
