`_`	(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).

Florence, Biblioteca Medicea Laurenziana, Plut. 89 sup. 57

Date:

s. XIII^med (the MS was glossed by the scribe in or after 1247; one of these glosses on f. 57r gives the mean position of the Sun for ‘anni perfecti 1294, 6 menses…’, i.e. 1295, but this gloss is in fact a replica of another gloss found in MS Paris, BnF, lat. 16200 (see), f. 46v, where it reads ‘anni perfecti 1994, 6 menses…’ meaning 1994 in the era of Nabonassar, so that ‘anni perfecti 1994’ corresponds to 1247/48 A.D. This is confirmed by another gloss by the scribe on f. 55v, which explicitly mentions the year 1247 (‘1246 completo’) – this gloss is also found in the Paris MS, f. 45v).

Prov.:

according to the title and the colophon of the Almagest, both added by a later hand, the MS belonged to one ‘Thadeus Chambinus … (?) de Florentia’ or ‘Thadeus Arduvinis de Florentia’, who is probably identical with the Florentine physician Taddeo (di Cambino) Arduini attested in the first half of the 15^th c.; Florence, convent of San Marco (cf. ex-libris f. 1r, late medieval hand).

Parchment, 100 f., a single hand, reserved initials.

Ptolemaica (single text).
