`_`	(the underscore) is the placeholder for exactly one character.
`%`	(the percent sign) is the placeholder for no, one or more than one character.
`%%`	(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).

[Colour scanned images of the textblock, some trimmed around the text area.]

Eleven works, many incomplete: Arabic. Date:

various dates between Friday, 1 Jumādā l-ūlā 721/29 May 1321 and 11 Jumādā l-thāniya 721/8 July 1321 (10r, 14r, 19r, 29r, 44v).

Or.:

al-Sulṭāniyya (10r, 14r, 19r); unknown scribe.

Prov.:

this manuscript is in earlier literature referred to as ‘ʿAbd al-Ḥayy 21’; Rashed described it as MS ʿAbd al-Ḥayy 678/55. At the moment scans of the separate works (sometimes incorrectly combined) are offered under the shelfmarks 673/50 to 678/55.

Cod.: paper, I+44 ff. (rectos foliated with Hindu-Arabic numerals in pencil just above and just left of the text area, sometimes covered by the restorations of the margins; catchwords). A naskh hand in black; mostly dotted ductus without diacritical signs; textual dividers in red or with red overlines. Diagrams in red and black with black labels; some empty spaces reserved for diagrams (31r–32r, 36r). Codex in poor condition and great disorder; many works incomplete, apparently due to to the loss of a considerable number of folios; moisture stains, occasionally affecting the readability; bottom of ff. 26r–v torn (last six lines lost); all margins restored with modern paper. Dimensions: 21.8×7.6 cm (Rashed, Les mathématiques infinitésimales II, p. 23); 33 lines per page.

Cont.: mathematics, astronomy, optics. — Index: Due to the great disorder of the codex, the order of the works as given here is not necessarily the original one. Ibn al-Haytham, Qawl fī Misāḥat al-kura (1r–4v, 13r–14r); Ibn al-Haytham, Qawl fī l-Hilāliyyāt (14v–16v); Ibn al-Haytham, Maqāla fī ʿIllat al-jadhr wa-iḍʿāfi-hi wa-naqli-hi (17r–19r); Ptolemaica (19v–26v, 5r–6v, 12v, 12r, 7v, 7r); Ibn al-Haytham, Qawl fī Muqaddimat ḍilʿ al-musabbaʿ (27r–v, unfoliated fragment); Ibn al-Haytham, Risāla fī l-Marāyā l-muḥriqa bi-l-quṭūʿ (31r–32v, 29r, fragments including the end); Ibn al-Haytham, Risāla fī ʿAmal dawāʾir ʿuẓām bi-āla ṣaghīra=Risāla fī Birkār al-dawāʾir al-ʿiẓam (29r–v, 8r–10r); Ibn al-Haytham, Qawl fī Tarbīʿ al-dāʾira (10r–11v, 30v, 30r); objection (iʿtirāḍ) against the preceding treatise, in the colophon ascribed to either Ibn al-Sumaysāṭī (who may be identical to al-Simyāṭī, for whom see MS Oxford, Bodleian, Thurston 3, ff. 103v–104r) or ʿAlī ibn Riḍwān (30r); Ibn al-Haytham, Risāla fī l-Marāyā l-muḥriqa bi-l-dawāʾir (33r–36v, 44r–v, beginning missing); al-Ahwāzī, part of his commentary on Book X of Euclid’s Elements (37r–43r; see Rashed, Les mathématiques infinitésimales III).
