“In vain would one look among them for makers of arrows, or javelins, or swords, or helmets, or armour, or shields; in short, for makers of arms, or military machines or any instrument of war, or even of peaceful objects which might be turned to evil purpose.” Philo, Quod omnis probus liber sit, in Complete Works, trans. F.H. Colson et al., 10 vols. (London: Heinemann, 1929–1961), p. 78.
