instance of the reign of Peroz, all through such an harmony with Eutychius that here two independent authors must necessarily have drawn upon one and the same original; and that original source can be no other than the production of Ibn Mukaffa. The abstract in Eutychius is very unequal being in some parts exhaustive, in others much abridged. The narrations as preserved in Tabari, which correspond to the statements in Eutychius and Ibn Kotaiba and which consequently go back to Ibn Mukaffa, are of a similar nature though Tabari gives in addition other parallel reports. Tabari, however, did not himself use Ibn Mukaffa's work, but for the History of Persia, among other authorities, employed by preference a younger work which represented another version together with excerts from the former. This can be inferred from the fact that the anonymous Codex Sprengers 30, which and Tabari are mutually independent, shows quite the same combination of two main sources and so far as the section in question goes, can be utilised and treated as a new manuscript of Tabari. Both have relied almost to the letter upon the presentment which emanated partly from Ibn Mukaffa and partly from another translator with the only difference that the anonymous writer is oftener more concise than Tabari. Again the version which does not proceed from Ibn Mukaffa is for the most part in accord with the epitome of the story of the Sasanides in the introduction to Yakubi's History of the Abbasides; there the excellent author occasionally subjoins extraneous information. More often than not this presentment is in touch with Ferdausi. I am unable to aver from whom has originated this other recension of the story of the Sasanides. We know indeed the names of a number of persons who redacted the History of Persia, originally in Pahlavi, for Arab readers. But though we can collect a few notices of some of the authors mentioned, we know nothing in particular about them and are completely in the dark about the special nature of their work. All that we can postulate as established is that they wrote posterior to Ibn Mukaffa. The latter is always mentioned in the first place. Muhammad bin Jahm who is regularly cited next after him and bears the surname of Bermaki, was a client of the Barmecides, who came to power a long while after the death of Ibn Mukaffa. Ifc may be supposed that they all laid under contribution the production of their celebrated predecessor. How they individually set about their work, whether perhaps some of them tapped non-Persian tradition; also, how far one or other of them utilized the novels of which there were probably many in Pahlavi--this we are no longer in a position to determine. Again this too remains a mystery whence Tabari came by most of the accounts touching the Persians, which are conspicuous by their absence in the anonymous Codex. To clear this whole ground it would appear to be expedient in the first
