`_`	(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).

Vatican, Biblioteca Apostolica Vaticana, Pal. lat. 1371

s. XIII¹ or possibly XII² for f. 41-97, with decoration probably added around the middle of the 13^th c. (f. 1-40, which form one codicological unit, are posterior to 1217, date of the translation of Alpetragius’s De motibus celorum by Michael Scot). F. 41-97 are dated to the 13^th c. by Haskins, to ‘12^e/13^e siècle’ by Pelzer, to the middle of the 12^th c. by Lemay, 464, and to the 13^th c. by Schuba (but Schuba was unaware of Lemay’s contribution). One argument towards a 12^th-c. dating is that the Arabic numerals used in the tables of the Almagest present, according to Burnett, a ‘striking similarity’ with those used in a psalter written in or shortly before 1153, most probably in Palermo under Roger II (Burnett, ‘Indian Numerals…’, 244; also Burnett, ‘The Use of Arabic…’, 47). If this MS was a later copy, one would expect the numerals to have been adapted, as happened in the other MSS of this text.

Or.:

Italy, certainly Palermo if the MS is to be dated to the 12^th c. (Lemay, 471, suggests that f. 41-97 were copied by or under the supervision of Hermann of Carinthia, whom he believes to be the translator of the Ptolemaic section).

Prov.:

Ulrich Fugger (d. 1584); Heidelberg, Bibliotheca Palatina; Vatican library in 1623.

Parchment, 99 f., several hands. The Ptolemaic section (f. 41-97) is copied by three hands and contains beautifully painted initials at the beginning of each book. Several folia are missing between f. 40-41 and after f. 97.

Astronomy and mathematics: Alpetragius, De motibus celorum (1r-34v); ‘Capitulum de inventione radicum et multiplicatione et divisione et diminutione et agregatione earum inter se et de aliis huismodi. Postquam tractavimus de his que superius dicta sunt…’ (35r-40v, end gone); Ptolemaica (41r-97v); added notes by a 13^th-c. hand (98r-98v), including a Greek-Latin astronomical glossary of 21 terms and planetary positions under the title ‘In die illa celum sic se habebat’; 13^th-c. (?) fragment of a text unrelated to the rest of the MS (99r-99v).
