`%%`	(two percent signs) is the placeholder for no, one or more than one character, but not for blank space (so that a search ends at word boundaries).

Single work with the later addition of an appendix from an alternative version of the same work: Arabic. Date:

undated; first half of the 6^th/12^th century, although Derenbourg gives the 8^th/14^th century.

Or.:

al-Andalus; copied by ʿAlī b. Aḥmad b. Mufarrij (fl. 530/1136) for his personal use (1r). The scribe can be identified as the Andalusi faqīh ʿAlī b. Aḥmad b. Mufarrij b. Ziyād al-Sayyārī who was active in 530/1136, when he also copied (khaṭṭa) Ibn Rushd al-Jadd’s (d. 520/1126) al-Bayān wa-l-taḥṣīl. Thus, Ibn Mufarrij was active during Jābir b. Aflaḥ’s lifetime (fl. first half of the 6^th/12^th century) or shortly after. It is very likely that this manuscript was copied when Jābir b. Aflaḥ was still alive, since the scribe refers to him as shaykh (1r), which suggests that Jābir b. Aflaḥ was still an elder person when the scribe copied the manuscript. The formula raḥimahu Allāh referring to Ibn Mufarrij is written on top of an erased one. Thus, it was changed upon Ibn Mufarrij’s passing away, what suggests that the manuscript was owned by him until his death or that the new owner knew him. On ʿAlī b. Aḥmad b. Mufarrij, see Ibn ʿAbd al-Malik al-Marrākushī, al-Dhayl wa-l-takmila li-kitābay al-Mawṣūl wa-l-Ṣila, ed. M. b. Sharīfa and I. ʿAbbās, 5 vols. (I, IV, V, VI, VIII), Beirut: Dār al-thaqāfa, n.d.-1984, and José Bellver, ‘The Arabic Versions’.

Prov.:

statements of ownership by Muḥammad b. ʿAlī b. Muḥammad b. Sūṣūr* (1r); by Ibrahīm b. Muḥammad b. Ibrahīm b. ʿAbd Allāh (1r; he may be the Mālikī judge and muftī of Fes ⟨Abū Isḥāq⟩ Ibrahīm b. Muḥammad b. Ibrahīm b. ʿAbd Allāh al-Yaznāsī (d. 794/1391) since there is a very blurred nisba on top of the statement that may be consistent with al-Yaznāsī; on him, see Muḥammad Makhlūf, Shajarat al-nūr al-zakiyya fī ṭabaqāt al-mālikiyya, 2 vols. Beirut: Dār al-kutub al-ʿilmiyya, 1424/2003); by Aḥmad b. Muḥammad* ⟨...⟩ al-Judhāmī (1r); and at least one other illegible statement of ownership (1r); a statement of purchase for Muley Muḥammad Naṣr Allāh by his servant Muḥammad b. ʿĪsā (1r; Muley Muḥammad Naṣr Allāh probably refers to one of the twelve Nasrid sultans named Muḥammad who ruled Granada from the 7^th/13 century to the 9^th/15^th century, and thus it is likely that this manuscript was part of the Nasrid palatine library); old shelfmarks: al-taʿlīm 1/4 al-ʿilm (in ghubār numerals) probably written by Muḥammad b. ʿĪsā (1r); V.I.IV.4 and Cod. 870 (1r); V.C.2., num. 44 with Latin title (2r); Escorial RBMSL Cod. 930 (1r, 150v).

Cod.:

paper, 150 ff. (foliated with Arabic-European numerals). A single clear brown naskh hand with letters fāʾ and qāf dotted according to the western custom; chapter headings and first words of paragraphs in bold without rubrics; partially dotted ductus with occasional vowels, hamzas and shaddas. Substantial figures in brown and red. Dimensions: 250x185 mm; 21 lines per page. Some moisture stains throughout.

Cont.:

astronomy. — Index: Ptolemaica (1r-140r and 142r-150v); table of elements and natures related to the planets (141v). Blank: 140v-141r.
