Zoomorphic initial “S” in the form of a dragon on fol. 7v, LJS 194, a 12th century copy of Pope Sylvester II’s Geometria. Collection of geometrical texts, including material from four chapters of the Isagoge geometriae; correspondence with Adelbaldus (also known as Adelbold or Albaldus, of Utrecht) about the area of isosceles triangles; and a treatise on the construction of astrolabes. Annotated in the 12th century and also by an unknown late 15th- or early 16th-century humanist who collated the text with other manuscripts and noted the classical sources in the text.Manuscript description and digital images: http://openn.library.upenn.edu/Data/LJSchoenbergManuscripts/html/ljs194.html -- source link
