youth who could not do all three was looked upon as uncultured. Nor could he hide his want of culture, since young men were continually called upon, both at home and at more or less public gatherings, to perform their part in the social entertainment.

A LESSON IN MUSIC AND LANGUAGE _Explanation_: At the right is the _paidagogos_; he is seated, and turns his head to look at his pupil, who is standing before his master. The latter holds a writing-tablet and a stylus; he is perhaps correcting a task. At the left a pupil is taking a music lesson. On the wall are hung a roll of manuscript, a folded writing- tablet, a lyre, and an unknown cross-shaped object. A LESSON IN MUSIC AND POETRY _Explanation_: At the right sits, cross- legged, the _paidagogos_, who has just brought in his pupil. The boy stands before the teacher of poetry and recites his lesson. The master, in a chair, holds in his hand a roll which he is unfolding, upon which we see Greek letters. Above these three figures we see on the wall a cup, a lyre, and a leather case of flutes. To the bag is attached the small box containing mouthpieces of different kinds for the flutes. Farther on a pupil is receiving a lesson in music. The master and pupil are both seated on seats without backs. The master, with head erect, looks at the pupil who, bent over his lyre, seems absorbed in his playing. Above are hanging a basket, a lyre, and a cup. On the wall is an inscription in Greek.]
