Of the musical recitations of portions of existing tragedies or of tragic episodes written for the occasion we possess even less knowledge. The passages selected or composed for this purpose were in all probability usually lyric, but we hear also of the chanting of iambics, as, for instance, in the case of the _Oedipus in Exile,_ in which Nero made his last appearance on the stage.[117] Of the part played by the chorus and of the structure of the librettos we know nothing; they may have been purely episodic and isolated or may, as in the _salticae fabulae,_ have been loosely strung together into the form of an ill-constructed play. That they were sometimes written in Greek is known from the fact that the line quoted by Suetonius from the _Oedipus in Exile_ mentioned above is in that language. Of the writers of this debased and bastard offspring of drama we know nothing save that Nero, who was passionately fond of appearing in them, seems also to have written them. (Suet. Ner. 39.) The tragic stage had indeed sunk low, when it served almost entirely for exhibitions such as these. Nevertheless tragedy had not ceased to exist even if it had ceased to hold the stage.[118] Varius and Ovid had won fame in the Augustan age by their Thyestes and Medea, and the post-Augustan decadence was not without its tragedians. One only is mentioned by Quintilian in his survey of Roman poetry, Pomponius Secundus. Of him he says (x. 1. 98), 'Of the tragedians whom I myself have seen, Pomponius Secundus is by far the most eminent; a writer whom the oldest men of the day thought not quite tragic enough, but acknowledged that he excelled in learning and elegance of style.' Pomponius was a man of great distinction.[119] His friendship for Aelius Gallus, the son of Sejanus, had brought him into disgrace with Tiberius, but he recovered his position under Claudius. He attained to the consulship, and commanded with distinction in a war against the Chatti in A.D. 50. Of his writings we know but very little. Of his plays nothing is left save a brief fragment[120] from a play entitled _Aeneas_; whether it dealt with the deeds of Aeneas in his native land or in the land of his adoption is uncertain, though it is on the whole probable that the scene was Italian and that the drama was therefore a _fabula praetexta_. Whether his plays were performed on the public stage is not quite clear. Tacitus tells us of riots in the theatre in A.D. 44,[121] when 'poems' by Pomponius were being recited on the stage. But the words used by the historian (_is carmina scaenae dabat_) point rather to the recitation of a dramatic solo than to a complete tragedy of the orthodox type. Pomponius, dramatist and philologist,[122] remains a mere name for us.
