Project icon: lavishly furnished initial letter with a painting of Ptolemy using an astrolab.

Ptolemaeus Arabus et Latinus

_ (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).

At the beginning and at the end, these placeholders are superfluous.

s. XIII.


this is one of two fragmentary folia extracted from the binding of a book. According to an accompanying typewritten note, these fragments were presented by the ‘Right Reverend Monsignor John Rothsteiner’ (probably John Ernest Rothensteiner, 1860-1936) to ‘the College’, i.e. Mundelein College, that merged with Loyola University in 1991. The same note says that the fragments ‘were found in the binding of a Greek Bible belonging to Erasmus’, which would rather mean a copy of one of Erasmus’s editions of the Greek New Testament. The other fragment, different in script, decoration and page-format, contains some Latin legal text.

Parchment, 1 f. (unnumbered), only the upper part of the page remains (125x165mm, 28 lines), a single hand.

Ptolemaica (single text).


None. My thanks to Ian Cornelius for calling my attention to this fragment and for kindly providing photographs and context.
