Burton cites a work called "Syntagma de Diis" ("A Compendium of the Gods") by Lilius Giraldus as his source for the existence of such a god; by this reference, Burton probably meant Giraldus' "Historia de diis gentium" ("History of the Pagan Gods"); but because Burton wrote in what he called an "extemporean" style, "quicquid in buccam venit" ("whatever came into his head"), Burton's quotations and references are not always reliable. Because of Burton's mixed Latin and English style, this passage may not say that there was a god "named" "Crepitus Ventris", (Latin for "intestinal noise"), but only that there was a god of intestinal noise. The Latin word "crepitus", moreover, did not exclusively mean the sound generated by intestinal gas; it referred to squeaks, groans, knocks, and any nondescript noise in general. In "The City of God", Augustine elsewhere refers to "crepitus cymbalorum", the clang of cymbals. Medical jargon gives the name "crepitus" to the creaking or popping noises made by the joints. The is "pēdere".
