[289] Shams-ed-doulah (according to Herbelot, Samsameddulah), son of Adhadededdulat, was the tenth prince of the Búyi dynasty. [290] Kazvin, a town in Persian Irak. [291] Hamdan, a town in Persian Irak, to the west of Kazvin, about 450 miles N. W. of Isfahan. [292] Herbelot states Baha-ed-Doulah to be son of Adhad-doulat, and brother of Samsameddulat. [293] Herbelot says, that Abu Alí entitled his great work _Canun fil thebi_, “Rule of Medicine;” this book has been abridged and commented by Said Ben Hebatallah, by Razi Ben al Khatib, and by another author, who has composed the _Mugiaz fil theb_. [294] We read in Abulfeda’s history (vol. III. p. 64): “In the year of the Hejira 414, A. D. 1023, Ala-ed-daula Abu Jafar, commonly called son of Kakuyah, took Hamdam from one of the Búyís, say Sama-ed-doulah Abúl Hasan, son of Shams-ed-Doulah.” [295] The biography of Avisenna involves a variety of events which cannot be here sufficiently developed for removing the obscurity attending the short account of our author. The name of Tájet-ud-doulah is not found in Abulfeda’s and Herbelot’s notice of the Shaikh Avisenna. [296] Adopting as true the year of his birth, as stated in the Dabistán (see p. 169), Abu Ali, according to the above date of his death, would have died in his ninety-first year. According to Abulfeda (see vol. III. p. 92), he died in his fifty-eighth year; Herbelot says, he died in the year of the Hejira 428, A. D. 1036, in the fifty-sixth year of his life. [297] Herbelot says that Avisenna wrote his biography himself; the French author mentions a life of the celebrated Muhammedan doctor, composed by doctor Giorgiani. * * * * *
