As we have already observed, and as we shall have occasion to speak further, this category of literary remains undoubtedly survived in the Musalman literature and partly in the literature of the Arabs. For the study of the Pahlavi literature this class of tracts has already evoked attention and has called forth several editions and translations. We notice that their interest goes beyond that of Pahlavi literature proper and they are important also for the history of the literature of Musalman nations. Moreover, they are of interest from a general point of view, for the study of Musalman culture. In fact, by their very character these works are brief catechisms with no pretensions to abstract theoretical acquaintance with the sacerdotal tracts, composing another important section of Pahlavi literature, but immediately connected with the daily ordinary life. It goes without saying that whoever read them in the original, their interest did not lie in their theoretical character, but that they were rendered into Arabic and modern Persian languages with a view to the same practical end. Hence however monotonous they are,[1] whatever wearisome character these books possess, they are of great interest for the purpose of comparison with similar productions of Musalman literature and for the purpose of establishing their influence in the unfolding of ethical ideas of the Musalman east, which are far from being clearly made manifest. This side of the question deserves, in my opinion, in these days ampler attention and research. [Footnote 1: See Noeldeke "_Persische Studien_" II, S.B.W.A, 1892, 29, Noeldeke remarks, with reference to this class of literature, "that the investigation of this fatiguing business demands an unusual amount of patience", see for instance, the comparison instituted between ethical norm in the Parsi and in the Musalman Literature by Darmesteter in _Revue Critique_, 21, 1-8.] 2. The second book in the Fihrist is attributed to a _Mobedan-mobed_ that is, head of the Parsi clergy, who in Arabic texts is sometimes called simply Al-Mobedan and whose name was not understood by Flugel[1]. The same word is met with in a mutilated form in another place in the Fihrist[2]. (119-20). [Footnote 1: Fugel took it for a dual, and consequently divided the name into two.] [Footnote 2: The book next following is called _Kitab kay Lorasp_ and apparently it had to do with questions connected with Persian literary tradition.]
