His name means "little Anthemius" and is a diminutive of his and his father's name Anthemius, in order to distinguish them both.
His life is known only from the Chronica Gallica of 511. He was sent by his father to Gaul with a powerful army, accompanied by three generals — Thorisarius, Everdingus, and Hermianus — in order to oppose the Visigoths then occupying Provence and threatening to conquer the Auvergne. He and his generals were defeated by the Visigothic king Euric near Arles and all four of them lost their wives. The Chronica, in entry 649, states:
Antimolus a patre Anthemio imperatore cum Thorisario, Everdingo et Hermiano com. stabuli Arelate directus est, quibus rex Euricus trans Rhodanum occurrit occisisque ducibus omnia vastavit
According to the Chronica, this event falls between the succession of Euric (467) and the war between Anthemius and Ricimer (471–472). It can probably be further narrowed to the period when Anthemius is known to have been organising a concerted effort to remove the Visigoths from Gaul between 468 and 471, a period during which an army led by the Briton Riothamus was defeated near Déols. It is not impossible that Anthemiolus' army was sent to reinforce Riothamus and that Euric defeated both forces in turn, probably in either 470 or 471.
