These facts are, it must at once be admitted, extremely favourable to the authenticity of the dramas; taken all in all they are clearly the work of a very considerable writer; in technique they are less finished than those of Kālidāsa; the Prākrit is clearly earlier than that of the works of Kālidāsa or the Mṛcchakaṭikā; the Svapnavāsavadattā is clearly the best, and it explains Vākpati and Rājaçekhara’s references. Bāṇa’s statement regarding the opening of the plays by the Sūtradhāra is proved by the dramas. There is also substantial evidence to be derived from the writers on rhetoric. Bhāmaha, who may belong to the beginning of the eighth century A.D., criticizes severely the plot of the Pratijñāyaugandharāyaṇa; Vāmana, in the eighth, cites from that play, the Svapnavāsavadattā, and the Cārudatta; Abhinavagupta (c. A.D. 1000) twice names the Svapnavāsavadattā, and mentions the Cārudatta. These references are not in themselves conclusive, for they do not mention Bhāsa as the author of the plays, even when these are named, [164] and not merely cited from or discussed, but they show that the critics knew and were prepared to cite these dramas, which means that they accepted the view that they were by an important author. The ascription of the Svapnavāsavadattā to Bhāsa gives us the right to accept his authorship of the rest if internal evidence supports it. That this is so is undeniable, even by those who suspect the attribution to Bhāsa; the coincidences in technique, in the Prākrits, in metre, and in style are overwhelming. Finally, there is the evidence of the Cārudatta; it is undeniably and obviously the prototype of the Mṛcchakaṭikā, and it proves, therefore, that the dramas are older than that work which was well known by Vāmana, and is certainly a good deal earlier. The arguments [165] against the authenticity are all inconclusive. They are based on the fact that a drama, Mattavilāsa, of Mahendravikramavarman, of the seventh century A.D. presents the same characteristics as regards the form of opening the drama as the plays of Bhāsa, and the suggestion that Rājasiṅha is to be identified with a prince of the south of that name (c. A.D. 675). The evidence is clearly inadequate; Bhāsa’s fame was evidently more prevalent in the south than in the north, for a scene from one of his plays has survived in a mutilated form in the popular theatre there, and it is easy to understand how a seventh-century writer imitated him in technique. Moreover, the imitation is very partial; the omission of the name of the author and the play is not followed, and this is certainly a sign of a later date for the Mattavilāsa. The guess regarding the identification of the king is without probative force, for the term seems deliberately vague, and is in keeping with the silence of the author regarding his own name and that of his drama. The introduction of immediate reality is incongruous, and, therefore, avoided. 2. THE DATE OF BHĀSA’S DRAMAS
