The reason for this is very plain. When a fable about a lion and a jackal was told (as in No. 157) to show the advantage of a good character, and it was necessary to choose a short title for it, it was called ’The Lion Jātaka,’ or ‘The Jackal Jātaka,’ or even ’The Good Character Jātaka’; and when a fable was told about a tortoise, to show the evil results which follow on talkativeness (as in No. 215), the fable might as well be called ‘The Chatterbox Jātaka’ as ‘The Tortoise Jātaka,’ and the fable is referred to accordingly under both those names. It must always have been difficult, if not impossible, to fix upon a short title which should at once characterize the lesson to be taught, and the personages through whose acts it was taught; and different names would thus arise, and become interchangeable. It would be wrong therefore to attach too much importance to the difference of the names on the bas-reliefs and in the Jātaka Book. And in translating the titles we need not be afraid to allow ourselves a latitude similar to that which was indulged in by the early Buddhists themselves. There is yet further evidence confirmatory of the Dīpavaŋsa tradition. The Buddhist Scriptures are sometimes spoken of as consisting of nine different divisions, or sorts of texts (Aŋgāni), of which the seventh is ’Jātakas,’ or ‘The Jātaka Collection’ (Jātakaŋ). This division of the Sacred Books is mentioned, not only in the Dīpavaŋsa itself, and in the Sumaŋgala Vilāsinī, but also in the Aŋguttara Nikāya (one of the later works included in the Pāli Piṭakas), and in the Saddharma Puṇḍarīka (a late, but standard Sanskrit work of the Northern Buddhists).[73] It is common, therefore, to both of the two sections of the Buddhist Church; and it follows that it was probably in use before the great schism took place between them, possibly before the Council of Vesāli itself. In any case it is conclusive as to the existence of a collection of Jātakas at a very early date. * * * * * The text of the Jātaka Book, as now received among the Southern Buddhists, consists, as will be seen from the translation, not only of the stories, but of an elaborate commentary, containing a detailed Explanation of the verse or verses which occur in each of the stories; an Introduction to each of them, giving the occasion on which it is said to have been told; a Conclusion, explaining the connexion between the personages in the Introductory Story and the characters in the Birth Story; and finally, a long general Introduction to the whole work. It is, in fact, an edition by a later hand of the earlier stories; and though I have called it concisely the Jātaka Book, its full title is ‘The Commentary on the Jātakas.’
