The rattle, said to be invented by Archytas, was the first toy of the infant. Other toys of various kinds were partly bought, partly made by the children themselves on growing older. We mention painted clay puppets, representing human beings or animals, such as tortoises, hares, ducks, and mother apes with their offspring. Small stones were put inside, so as to produce a rattling noise; which circumstance, together with the fact of small figures of this kind being frequently found on children's graves, proves their being toys. Small wooden carts, houses and ships made of leather, and many other toys, made by the children themselves, might be instanced. Up to their sixth year boys and girls were brought up together under their mother's care; from that point their education became separate. The education proper of the boy became a more public one, while the girl was brought up by the mother at home, in a most simple way, according to their notions. From amongst the domestic slaves a trustworthy companion was chosen for the boy. He was, however, not a tutor in our sense, but rather a faithful servant, who had to take care of the boy in his walks, particularly on his way to and from school. He also had to instruct his pupil in certain rules of good behavior. The boy had, for instance, to walk in the street with his head bent, as a sign of modesty, and to make room for his elders meeting him. In the presence of the latter he had to preserve a respectful silence. Proper behavior at table, a graceful way of wearing his garments, etc., might be mentioned as kindred subjects of education. Boys were accompanied by pedagogues up to their sixteenth year. The latter appear frequently in vase-paintings, and are easily recognizable by their dress, consisting of chiton and cloak, with high-laced boots; they also carry sticks with crooked handles, and their hair and beards give them a venerable aspect; while their pupils, according to Athenian custom, are clad more lightly and gracefully. The pedagogue of the group of the Niobides is well known.
