Mosaique du musee national du Bardo _ Tunis
In this detail from a larger mosaic in the Römerhalle, Bad Kreuznach (Germany), the Thraex attacks with the sword in his left hand, which usually would hold the shield. Gladiators were trained to fight against those who were right-handed, and it was the right-hand side that was protected. It must have been disconcerting, therefore, to confront a left-handed opponent, who would have the advantage.
