Three competing Second Sphinx theories at Giza evaluated against evidence. Filippo Biondi appeared on the Matt Beal Limitless podcast on March 26, 2026, claiming a second Sphinx buried under a 108-ft mound on the The Great Pyramid of Giza using SAR radar scans Biondi claimed 80% confidence in the second sphinx identification, citing geometric match with the Great Sphinx; no excavation, peer review, or Egyptian authority confirmation has been conducted A 1929 aerial photo of the The Great Pyramid of Giza by Hermann Junker (published through the Austrian Academy of Sciences) shows the mound Biondi identified was not present or was extremely small, indicating it formed in the 20th century

Three Second Sphinx theories circulate at Giza, but none peer-reviewed or excavated. Filippo Biondi claimed 80% confidence in one buried under a 108-ft mound via SAR radar (March 2026 podcast). Yet a 1929 Hermann Junker aerial photo shows that mound didn't exist then. Egyptologist Dr. Peter Brand identifies it as a 20th-century debris ramp. Fascinating debate, but the evidence isn't there yet. 🏛️
