The following image provides visual illustration of the imitative aspect of Roman oratory. The school-boy depicted will have entered into the stage of his education in which he rehearses declamationes, or practice orations on stock themes. The r hetorical training is accompanied by, and inseparable from, formal techniques of dramatic delivery. Here the boy assumes the formal posture of public address. Compare such details as hand gesture, and the position of head, shoulders, hips and feet with st atues of Titus and Caligula represented in similar postures.
