Abl-Hasan Mihyar Ibn Mirzawaih, a native of Dadam and secretary for Persian language was a Fire-worshipper, but afterwards adopted the Moslem faith. It is said that he made his profession to Sharif ar-Rida who was his professor and under whom he made his poetical studies. It seems, however, the conversion of Mihyar was only nominal. Ibn al-Athir al-Jazari says in his Annals that one Ibn Burhan said to him. "Mihyar, by becoming a Musalman you have merely passed from one corner of hell to another." "How so?" said Mihyar. Ibn Burhan replied: "Because you were formerly a fire-worshipper and now you revile the companions of our blessed Prophet in your verses." (P. 517.) Ibn Khallikan adds that "Mihyar and Mirzawaith are both Persian names. Their signification is unknown to me." VOLUME III. Instances of hybrid compound names, the Iranian component being retained.

[Sidenote: Old castles.] Istakhri refers to the castle of Jiss in the district of Arrajan about which we have a more exhaustive notice by other writers. "Here lived the Magians," says Istakhri, "and here also are to be found memorials of the past of Persia. The place is strongly fortified. The castle of Iraj is also strongly fortified. The fastnesses which cannot be subjugated are so many that it is not possible to detail them."
