According to Iranians, al-Bīrjandī is the correct orthography and not al-Birjandī as the authors write. Further, his actual name was not ‘Abd al-’Alī, as the authors say (p. 3), but Nizām al-Dīn ‘Abd al-’Alī see BehniaReza Mohammad, Bīrjand, the jewel of the desert (Tehran, 2002), 546.

See for detail SalibaGeorge, A history of Arabic astronomy (New York, 1994), 250–2, 85–112. This is a collection of his major publications on the Islamic planetary theories. A number of papers in this book deal in details with the works of al-Tūsī's School at Marāgha, in which the non-Ptolemaic model of planetary motion was established.

Actually his model was originally invented by al-'Urdīal-Dīn Mu'ayyad (d. 1266), an instrument maker at the Marāgha observatory; cf.Ansari, op. cit. (ref. 2), 273et seq., and Saliba, op. cit. (ref. 4), 119–34.

For the corresponding Arabic and Persian sources, see AnsariS. M.

In Indian manuscript collections there are extant three copies of Tadhkira, and five copies of al-Bījandī'sCommentary, of which one manuscript was transcribed presumably from the autograph manuscript.
