Nec arare terram aut exspectare annum tam facile persuaseris quam vocare hostem et vulnera mereri. pigrum quin immo et iners videtur sudore adquirere quod possis sanguine parare.
(Tacitus, Germ. 14.5)
Nor could you so easily persuade them to cultivate the ground, or to await the return of the seasons and produce of the year, as to provoke the foe and to risk wounds and death: since stupid and spiritless they account it, to acquire by their sweat what they can gain by their blood. (tr. Thomas Gordon)
