teach both music and literature, and whose Maricas,
who was none other than Hyperbolus in disguise,
asserts that he knows nothing of music but letters.
again in more than one of his plays
shows that boys were trained in music from remote
antiquity, while in the Hypobolimaeus
an old man, when a father claims his son from him,
gives an account of all expenses incurred on behalf
of the boy's education and states that he has paid
out large sums to musicians and geometricians.
