The reverse legend on this very rare issue translates as 'Public sacrifices have been made to holy Jupiter, the best and greatest, for the well-being and the safe return [of the Emperor]'. These were vows undertaken in anticipation of Augustus' departure to Gaul in 16 BC, where for the next three years he supervised campaigns against tribes near the Rhine and in the Alps and initiated a great reorganization program for the northwestern provinces.
