`_`	(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).

Zurich, Zentralbibliothek, B.244

Date:

s. XV^ex (in or after 1489 for the Ptolemaic section, see below; f. 24-92 copied in 1490).

Or.:

f. 24-92 copied by Johannes Och of Wimpfen (Baden-Württemberg) in St Gall (f. 92rb: ‘Finitum in profesto Sancti Galli per me Ioannem Och de Wimppinna anno domini M^oCCCCLXXXX^o’).

Prov.:

Christoph Klauser (16^th c.), who added the table of contents f. Ir and copied f. 5r-7r and 89va-90v.

Paper, I+92 f. (new foliation in upper right corner, as in Mohlberg), four hands: I, f. 1r-4r; II [Christoph Klauser], f. 5r-7r and 89va-90v; III, f. 11r-19v; IV [Johannes Och], f. 24r-89va and 91r-92r. The MS has been damaged (apparently by water), making the top four or five lines of each page partly illegible in the first part (f. 1-19). Several folia are missing before f. 11.
