Kitāb Madkhal Kūshyār wa-Risālah fī al-ḥisāb.

Ms. codex.

Title from inscription on fol. 1a.

Physical description: Written in black ink with use of red (see records for each text). Contains tables. Dark cream paper with thick laid lines and pulp visible. Magical(?) square on fol. 1a.

Inscription in Western numerals in black ink on the upper left corner of the upper cover (corresponds to Brill's list. See Houtsma, M. Th. Catalogue d'une collection de manuscrits arabes et turcs, no. 502).

Origin: Last text apparently completed at the end of Shawwāl 661 [Sept. 1263] in Khwārazm (see end of text, fol. 51a).
