Collation Model for LJS 26: Algorismus ; Tractatum de sphaera.

Contributor

Abstract

Treatise on the fundamentals of arithmetic (Algorismus), followed by a treatise on cosmography that describes and illustrates the Ptolemaic model of a spherical earth divided into climactic zones at the center of the concentric spheres of the universe. The second treatise has marginal notes in the same ink and possibly hand as the text, as well as notes in a later cursive hand in faint ink and a bifolium written in this later hand bound in (f. 23-24).
