Beside the succession myth that makes Geb father of Osiris, Isis, Set and Nephthys, Egyptian cosmogony preserves a second and stranger account of him, one told through his sacred animal rather than his children. Geb's hieroglyph is a goose, and one strand of Egyptian creation myth identifies him with Gengen Wer, the Great Cackler, the primeval goose whose honk broke the silence of the first waters and who laid the cosmic egg from which the sun itself emerged. Some tellings give the same act to an ibis associated with Thoth rather than to Geb's goose, and Egyptian religion tolerated the two accounts side by side rather than resolving which bird actually laid the egg, consistent with its general comfort holding multiple creation traditions from different cult centres as simultaneously true. The epithet stuck to him permanently: temple and funerary texts continued to address Geb as the Great Cackler long after the succession myth had become his most quoted story, and the association fixed the goose as his standing iconographic marker even in scenes that have nothing to do with the egg itself. The myth gives Geb a second and older role distinct from earth god and ousted king, standing near or at the very beginning of the ordered world's coming into being rather than only inheriting it.
