26 We shall not here mention Laverna, goddess of thieves, the Bellonae, Discordiae, Furiae thieves, and we pass by in utter silence the unpropitious deities whom you have set up. We shall bring forward Mars himself, and the fair mother of the Desires; to one of whom you commit wars, to the other love and passionate desire. My opponent says that Mars has power over wars; whether to quell those which are raging, or to revive them when interrupted, and kindle them in time of peace? For if he claims the madness of war, why do wars rage every day? But if he is their author, we shall then say that the god, to satisfy his own inclination, involves the whole world in strife; sows the seeds of discord and variance between far-distant peoples; gathers so many thousand men from different quarters, and speedily heaps up the field with dead bodies; makes the streams flow with blood, sweeps away the most firmly-founded empires, lays cities in the dust, robs the free of their liberty, and makes them slaves; rejoices in civil strife, in the bloody death of brothers who die in conflict, and, in fine, in the dire, murderous contest of children with their fathers.
