Overview
The Omar account is associated with Ouropocari fall on the Essequibo River in Everard im Thurn's 1883 collection, quoted at length by Walter Roth in 1915. Omars are described with bodies resembling exaggerated crabs or fishes, living beneath rapids and dragging passing boats underwater. In the particular Ouropocari story, the being eats rotten wood. It mistakes canoes for drifting logs; the occupants drown even though the story explains the attacks through this mistaken food recognition. The combination of a rapid, a submerged appetite and a canoe mistaken for wood ties the encounter to the practical dangers of a named river passage.
An Akawaio piai, written Ackawoi peaiman in the historical witness, prepares two sticks used to make fire by friction. He wraps them carefully so water cannot spoil them, then dives into the falls and enters Omar's belly. There he discovers accumulated rotten wood. Setting the stockpile alight causes such pain that Omar rises to the surface, expels the piai and dies. Roth follows the quotation with his own comparison between the name omar and an Arawak fish name, and with a speculative parallel to Jonah; neither comment establishes the monster's derivation. The episode differs from the Moruca Ho-aránni story, where a swallowed piai also uses fire but dies after reaching home. Here the quoted story ends with the monster's death and the man's release.
The original 1883 book also uses omar in contexts unlike the canoe-swallowing rapids monster. Near Warrapoota, companions search by torchlight after hearing what they call an omar; im Thurn interprets tracks found the next morning as those of a paca. On the Takootoo journey his companions call porpoises omars or water-women and say that they wear dresses. These observations show variation within this writer’s use of the term, rather than proving that the Ouropocari creature has one fixed anatomy or that every reported omar is the same being. The companions are not individually named in these passages.
Direct comparison with the original confirms the complete fire-in-the-belly episode and its ending: the piai is expelled and Omar dies. Im Thurn himself follows it with parallels to Jonah, Hiawatha and other swallowed figures, suggesting independent development from common experiences. Roth’s later comparison therefore belongs to an already comparative chain of publications. Neither author supplies evidence establishing diffusion or the first origin of the story.
Origins & earliest records
Im Thurn's Among the Indians of Guiana appeared in 1883. Roth reproduces its page 385 account in section 181 of his 1915 inquiry, page 244, retaining the Ouropocari locality. These are dated publication witnesses; they do not establish when the account originated or how widely the name was used.
Records & interpretation
Roth’s quotation has now been checked against the complete original1883 Ouropocari episode385–386. Additional passages19,40 and352–353 show different applications of omar. Neither the named protagonist’s community nor the collector’s traveling companions establish the identity of an otherwise unnamed narrator. Colonial claims that all Indigenous thought is uniform or unscientific are not adopted.

An inquiry into the animism and folk-lore of the Guiana Indians
Washington, D.C.: U.S. Government Printing Office,1915; selected Cornell scan. Catalogue year independently checked; field preface dated Pomeroon,June1913.
- The quoted Essequibo account gives Omar a fish/crab-like body and mistaken attacks on boats taken for rotten logs. An Ackawoi peaiman enters it with protected fire-making wood and burns its stored timber. Omar expels him at the surface and dies.
Section181, printed p.244; complete quotation credited im Thurnp.385
- Roth notes that his only named record is im Thurn’s and speculates about pirai fish and a possible Jonah wordplay. These are the compiler’s explanatory possibilities, separate from the narrated Ouropocari event.
