The battle has been identified tentatively as the great vistory of Gaius Marius over fierce Teutonic tribes in Lombardy in 101 B.C. The tribes of the Cimbri had crossed the Alps near Trent and invaded the Veneto, whose mild climate and delicacies reputedly sapped their strengh. Their defeat saved Rome from conquest. The picture is from a series of ten canvases painted about 1725-1729 to decorate the main room of the Ca'Dolfin, Venice.
