Sobek is unusual among Egyptian gods in having his living cult described in detail by outside visitors rather than only by Egyptian priests writing for other Egyptians. Herodotus, touring Egypt in the fifth century BCE, reports that at the city later called Crocodilopolis the local sacred crocodile was kept tame in a temple pool, fed bread, meat, and wine brought by attendants, and adorned with earrings of glass and gold and bracelets around its forelegs, treatment Herodotus contrasts pointedly with other Egyptian regions where crocodiles were hunted and eaten rather than revered, evidence he offers of how sharply Egyptian religious practice could vary by locality even within a shared broader culture. Strabo, writing his Geography under Roman rule some four centuries later, describes visiting the same Faiyum region and being shown a specific sacred crocodile, which priests summoned to the water's edge and fed by hand while paying foreign tourists watched, an early and remarkably literal instance of religious tourism organized around a living cult animal.
Both accounts describe practice rather than belief, and neither writer had access to the theological reasoning behind Sobek's worship, but together they give Sobek something few Egyptian gods possess: independent, dated eyewitness testimony from outside the tradition, confirming that the tending of living sacred crocodiles was a real, organized temple practice rather than a later exaggeration, even if the two writers' emphases, wonder in one case and something closer to spectacle in the other, differ.
