European anecdote credits Gambrinus with the invention of beer. Aventinus attempted to reconcile this account with much older stories attributing its origin to Osiris' agricultural teachings. In Aventinus' chronicle, Gambrivius was the paramour of Osiris' wife and sister, Isis. It was by this association, he says, that Gambrivius learned the science of brewing (cf. myths of the theft of fire). Aventinus' account of Gambrivius contributed to the reverence for Osiris and Isis held by 17th-century European scholars. Perceiving Osiris and Isis as "culture bearers" enabled a willingness to see historical connections where there were none. The 59th stanza of the English drinking ode "The Ex-ale-tation of Ale", written by Peter Mews, evidences a British appropriation of the myth:  According to Aventinus, Gambrivius is a seventh-generation descendant of the Biblical patriarch Noah. By incorporating earlier myths recorded by Tacitus, Aventinus reckoned that Gambrivius was the fifth son of Marso (Latin: Marsus), who was the great-grandson of Tuisto, the giant or godly ancestor of the Germanic peoples whom Tacitus mentions in "Germania". Tacitus alludes to an earlier source (Strabo) who lists tribes called the "Gambrivii" and the "Marsi" among the peoples descended from Tuisto: the offspring or subjects of Gambrivius and Marsus, respectively. Gampar claims new lands east of the Rhine, including Flanders and Brabant, and founds the towns of Cambrai and Hamburg. The names of both these towns were theorized to be cognates of "Gambrivius", as one of Hamburg's ancient Latin names was alleged to be "Gambrivium". One of Aventinus' sources was "Officina" (1503), an encyclopedia compiled by French scholar Jean Tixier de Ravisi. This work purported that Tuisto and Gambrivius were giants descended from Noah. But Jean Tixier had only catalogued and reported a conjecture made in the name of the Hellenistic-era historian Berossus, by the fraudster Annio da Viterbo (1498), who had previously used the same hypothesis to postulate an ancestry for the Gauls. Some Francophone and Germanophone scholars reject the others' claim to Gambrinus as an appropriation of one of their own cultural heroes.
