"Be brave, my heart [wrote the poet and mercenary Archilochus]. Plant your feet and square your shoulders to the enemy. Meet him among the man-killing spears. Hold your ground. In victory, do not brag; in defeat, do not weep. The ancients resisted innovation in warfare because they feared it would rob the struggle of honor. King Agis was shown a new catapult, which could shoot a killing dart 200 yards. When he saw this, he wept. "Alas," he said. "Valor is no more."
