Sophistic proceeded for the most part upon the old lines. Its literary compositions preserved the old name, “exercises” (μελέται), as though they were still the rehearsals of actual pleadings. They were divided into two kinds, _Theses_ and _Hypotheses_, according as a subject was argued in general terms or names were introduced.[147] The latter were the more common. Their subjects were sometimes fictitious, sometimes taken from real history. Of the first of these there is a good example in Lucian’s _Tyrannicide_: the situation is, that a man goes into the citadel of a town for the purpose of killing a tyrant: not finding the tyrant, the man kills the tyrant’s son: the tyrant coming in and seeing his son with the sword in his body, stabs himself: the man claims the reward as a tyrannicide. Of the second kind of subjects, there are such instances as “Demosthenes defending himself against the charge of having taken the bribe which Demades brought,”[148] and “The Athenians wounded at Syracuse beg their comrades who are returning to Athens to put them to death.”[149] The Homeric cycle was an unfailing mine of subjects: the Persian wars hardly less so. “Would you like to hear a sensible speech about Agamemnon, or are you sick of hearing speeches about Agamemnon, Atreus’ son?” asks Dio Chrysostom in one of his Dialogues.[150] “I should not take amiss even a speech about Adrastus or Tantalus or Pelops, if I were likely to get good from it,” is the polite reply. In the treatment of both kinds of subjects, stress was laid on dramatic consistency. The character, whether real or supposed, was required to speak in an appropriate style.[151] The “exercise” had to be recited with an appropriate intonation.[152] Sometimes the dramatic effect was heightened by the introduction of two or more characters: for example, one of the surviving _pièces_ of Dio Chrysostom[153] consists of a wrangle in tragic style, and with tragic diction, between Odysseus and Philoctetes. This kind of Sophistic has an interest in two respects, apart from its relation to contemporary life. It gave birth to the Greek romance, which is the progenitor of the mediæval romance and of the modern novel:[154] a notable example of such a sophistical romance in Christian literature is the Clementine Homilies and Recognitions; in non-Christian literature, Philostratus’s Life of Apollonius of Tyana. It gave birth also to the writings in the style of ancient authors which, though commonly included in the collected works of those authors, betray their later origin by either the poverty of their thought or inadvertent neologisms of expression: for example, the Eryxias of Plato.[155]
