^The earliest certain evidence of the existence of Mogontiacum is the account of the death and funeral of Nero Claudius Drusus, brother of the future emperor, Tiberius, given in Suetonius' life of Drusus. Few leaders have been as loved and as popular as Drusus. He fell from his horse in 9 BC, contracted gangrene and lingered several days. His brother Tiberius reached him in just a few days riding post-horses over the Roman roads and served as the chief mourner, walking with the deceased in a funeral procession from the summer camp where he had fallen to Mogontiacum, where the soldiers insisted on a funeral. The body was transported to Rome, cremated in the Campus Martis and the ashes placed in the tomb of Augustus, who was still alive, and wrote poetry and delivered a state funeral oration for him. If Drusus founded Mogontiacum the earliest date is the start of his campaign, 13 BC. Some hypothesize that Mogontiacum was constructed at one of two earlier opportunities, one when Marcus Agrippa campaigned in the region in 42 BC or by Julius Caesar himself after 58 BC. Lack of evidence plays a part in favoring 13 BC. No sources cite Mogontiacum before 13 BC, no legions are known to have been stationed there, and no coins survive.[This quote needs a citation]

^A second hypothesis suggests that Moguns was a wealthy Celt whose estate was taken for the fort and that a tax district was formed on the area parallel to other tax districts with a -iacum suffix (Arenacum, Mannaricium). There is no evidence for this supposedly wealthy man or his estate, but there is plenty for the god. According to Carl Darling Buck in Comparative Grammar of Greek and Latin, -yo- and -k- are general Indo-European formative suffices and are not related to taxes. As the loyalty of the Vangiones was unquestioned and Drusus was campaigning over the Rhine, it is unlikely Mogontiacum would have been built to collect taxes from the Vangiones, who were not a Roman municipium.
