`_`	(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, Chigi F.IV.48

Date:

s. XII^ex-XIIIⁱⁿ (c. 1200) for f. 35-89 (information Stefan Georges).

Prov.:

Athanasius Kircher, who addressed the whole MS to Pope Alexander VII in 1662.

Parchment, 89 f. (new printed foliation in lower right corner), 170x115mm. MS made of three parts, each copied by a single neat hand. The third part (f. 35-89, late medieval foliation 23-77, initials roughly painted in red and green, titles in red, 30-31 lines) contains the Ptolemaic section only. The second part (f. 14-34, 12^th c., late medieval foliation 1-21) contains Hermann of Reichenau’s texts on the astrolabe (De mensura astrolabii, De utilitatibus astrolabii and De horologio viatorum) and a few chapters from the old corpus on the astrolabe. The first part (f. 1-13) is Athanasius Kircher’s presentation of these two old MSS to Alexander VII (cf. f. 2r: ‘Duo tractatus in hoc presenti codice B. P. continentur, quorum prior est de compositione astrolabii, alter Quadripartitum Ptolomaei de iudiciis astrorum in 4 libros divisus…’). The third part, made of seven signed quires of eight folia each plus one bifolium at the end, lacks one folio at the beginning and one bifolium between f. 83 and 84 (thus the quires are as follows: f. 35-41, 42-49, 50-57, 58-65, 66-73, 74-81, 82-85 and 86-89). The single late medieval foliation of f. 14-89 shows that the two parts were already bound together at an early date, by which the bifolium between f. 83 and 84 had already been lost.

Ptolemaica (single text) (f. 35-89). Blank: 89.

The text has two lacunae: (1) the beginning of the chapter index (and work title?), due to the missing folio before f. 35; (2) the section III.14-IV.7, due to the missing bifolium between f. 83 and 84 (‘… contra naturam sunt committent, mollos, effeminati, licita transgredi… /84r/ … in nativitate itidem si hoc ab ascendente prodite videantur…’). A few short marginal notes by a late medieval hand.
