Two of these manuscripts are in the Bibliothèque Nationale, in Paris (_Fond Syriaque_, Nos. 306 and 325). A translation of the Arabic (Carshuni) texts in these manuscripts relative to the Yezidis was published by Professor E. H. Browne in an appendix to O. H. Parry, _Six Months in a Syrian Monastery_, 1895. Professor Browne at that time proposed to edit the Arabic text (see J.-B. Chabot, _Journal Asiatique_, 1896, ix^e série, T. 7, p. 100); but so far as I can ascertain this intention has not been carried out. The manuscript translated by Browne, which according to Parry (_loc. cit._, p. 357) was written by a native of Mosul, seems to be closely related to that translated below. There are, however, some differences in contents and arrangement: my copy is divided into the Book of Revelation, the Black Book, and an Appendix; while Browne’s embraces the Book of Revelation which corresponds to that in my manuscript), and two other “Accounts,” the greater part of which is contained in the Black Book of my text, and the rest in the Appendix. Further, in my manuscript _Al-Jilwah_ immediately follows the Introduction; while in Browne’s the discussion of the sacerdotal system, the petition to the Ottoman government, and some other matters, are inserted between the Introduction and _Al-Jilwah_. In Browne’s, moreover, the Poem in Praise of Šeiḫ ‘Adî, and the Principal Prayer (in Kurdish) are absent, while the petition to the Turkish government is briefer, and lacks articles iv and xiv. The text of this petition, in its original form, was published by Lidzbarski in _Z D M G_, LI, 592 ff., after a manuscript in Berlin which was procured from Šammas Eremia Šamir. Two Syriac texts have also been printed. The first, edited and translated by J.-B. Chabot in the _Journal Asiatique_, 1896 (ix^e série, T. 7), p. 100 ff., from the Paris manuscripts referred to above, corresponds, with slight variations, to the second “Account,” of Browne (Parry, _loc. cit._, pp. 380-87). The second was published with an Italian translation, by Samuel Giamil, under the title, _Monte Singar; Storia di un Popolo Ignoto_ (Rome, 1900), from a manuscript copied for him in 1899 from an original in the monastery of Rabban Hormizd. The author of this work, a Syrian priest, Isaac, lived for a long time among the Yezidis, and not only had unusual opportunities of observation, but, as is evident from several anecdotes, possessed their confidence and esteem in a singular degree. His work is in catechetical form: a youthful Yezidi inquirer questions a teacher about the beliefs, traditions, and customs of his people, and the answers contain the fullest exposition of these matters we at present possess. Occasionally the author falls out of his role, and lets it appear that the questioner is no other than Priest Isaac himself.
