In his time Baron Rosen called attention to quotations from a certain _Book of Taj_ in _Uyunal Akhbar_ of Ibn Qutaiba.[1] These quotations are only to be found in the first part of the _Uyunal Akhbar_. All these quotations, eight in number, bear a didactic character, and excepting three, refer back to Kisra Abarviz and contain his testament to his sons (two), secretaries, treasurers and _hajibs_. Of the remaining three one bears on general maxims of practical politics. Another is a testament of an ancient Persian king to his Wazir. And the third is a maxim of one of the secretaries of a king. In this manner all these citations are of an ethicodidactic nature; only they have been invested with a historical environment and under ordinary circumstances would represent the general type of writings on political conduct for rulers, standing for the class of literature designated _Furstenspiegel_. A similar class of citations is preserved in the "speeches from the throne" and the counsels of the Sasanian kings which we come across in various Arab historical and anthological works bearing on Sasanian Persia, as also in the Shah Nameh. [Footnote 1: Baron Rosen, Zur arabischen Literatur geschichte der altern zeit, 1. Ibn Qutaiba; _Kitab Uyunal Akhbar_ (Melanges Asiatiques, VIII, 1880, 745-779, especially 774-775). These citations correspond to those in the edition of Brockelmann as follows: 21, 12-16; 27, 11-15; 32, 2-8; 44, 13-45, 4; 67, 13-66, 8; 84, 8-16; 107, 2-17; 120, 16-121, 5.] Gutschmid already noticed in his time that by the Persian historians to each Sasanian ruler was ascribed a maxim and indicated that with reference to Ardashir and Anoshiravan these maxims may be taken as the basis since the _Book of Counsels_ of the former was well-known and a large number of edifying proverbs of the latter had found admittance into the national language.[1] Let us add that, as we showed above, there has been preserved a similar class of _Books of Counsels_, the reputed author of which is Anoshiravan. The putative dicta of the other Sasanian kings Gutschmid considered as fabricated being designed to be brief characterisations of each of them. Gutschmid further advanced the conjecture that these apophthegms formed the texts under the portraits of the kings in the book which was used by Hamza Ispahani[2] and which was seen by Masudi.[3] According to the information supplied us by the latter (Masudi) he saw this book in Istakhr in an aristocratic Persian family, and that it included, besides information of a scientific character, the history of the Persian kings and their reigns and a description of the monuments erected by them.[4] In the book were the portraits of the Sasanians and it was based on the documents found in the royal archives. And the portraits also were prepared from the materials deposited there. The book was completed in A.H. 113 (A.D. 731), and it was translated for the Khalif Hisham from the Persian into the Arabic language.
