In the corresponding antistrophé Gamma was similarly coupled with the seven vowels, and so on apparently through the alphabet. During the song, which was set to excellent music, the members of the chorus, dressed to represent the letters quite clearly, and no doubt posturing in the right attitude, would form themselves into the required pairs. Thus, during the first line Beta and Alpha would come together, during the second Beta and Ei, and so on. After this song came a lecture on the vowels, in iambic verse, the chorus being told to repeat them one by one after the speaker. There seems to have been a plot of some sort in this extraordinary drama, but the main interest was, no doubt, the spelling. Opportunities were also taken for describing the shapes of the letters, the audience having to guess what letter was intended. This kind of alphabetical puzzle seems to have caught the popular fancy at Athens, for Euripides, Agathon, and Theodektes all employed it. In each case the concealed word was “Theseus.” Euripides’ description, if it be his, may be rendered thus:―― First, such a circle as is measured out By compasses, a clear mark in the midst. The second letter is two upright lines, Another joining them across their middles. The third is like a curl of hair. The fourth, One upright line and three crosswise infixed. The fifth is hard to tell: from several points Two lines run down to form one pedestal. The last is with the third identical. In the same spirit, Sophocles, in his satyric drama _Amphiaraos_, introduced an actor who represented the shapes of the letters by his dancing.[240] Periclean Athens seems to have taken a very keen interest in matters of spelling: the audience must all have known their letters, or such devices could never have become so popular. Kallias’ play is the ancestor of such books as _Reading without Tears_. His dramatic presentation of the process of spelling must have caught the imagination and impressed the memory of many Athenian boys. It may even be suspected that his method was adopted in enterprising schools, and spelling lessons were conducted to a tune, perhaps even accompanied by dancing.[241] The tunes of Kallias were highly praised, and were, no doubt, very different from the monotonous drone which announces to the outside world the presence of a Board School.
