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.

Work A.1.5

Almagesti (tr. Erasmus Reinhold)


‘(ed. Wittenberg 1549) Primus liber Magnae constructionis Ptolemaei. (45r) Optime mihi videntur hi, qui dextre philosophati sunt, separasse speculativam philosophiae partem ab activa… (47r) Caput I. De ordine huius doctrinae. Initium autem erit huius operis, haec consideratio, quomodo se tota terra universaliter habeat ad totum coelum — in qua aequinoctialis nusquam ad horizontem inclinat. Ad lectorem studiosum. Deo iuvante in proxima aeditione hanc institutam explicationem nostram rudiorem perpoliemus, et adiungemus reliqua ex Theone, quae ad Ptolemaei sententiam penitus intelligendam aliquid momenti adferunt, interea bene vale et hisce feliciter fruere. Laus Deo.’


Book I only, together with Reinhold’s annotations and comments both in the margins and in the text (in the latter case in italics), some of which borrowed from Theon of Alexandria’s commentary.


Translated from the Greek by Erasmus Reinhold, who published it together with the Greek text (from ed. Basel, Johannes Walderus, 1538) in 1549. Reinhold dedicated the work to Christoph von Karlowitz (1507-1578), a diplomat and correspondent of Philipp Melanchthon and Joachim Camerarius.
