**Walter Burley**  
C.S. Peirce

Oxford, England, 1442  
This 15th-century copy of a commentary by the 13th-century Oxford logician Walter Burley (or Burleigh) on the "ancient art" (viz. logic) of Porphyry and Aristotle contains notes of three kinds. The body of the text has elicited marginal annotations by a near-contemporary reader. On the fly-leaf there are additional notes, including two items pasted in, one of which features penmanship practice and an image of a person. Finally, this copy is of special interest because of notes made by a much later owner: the American philosopher Charles Sanders Peirce (1839-1914), whose papers are also held at Houghton Library. On a fly-leaf added in modern times Peirce describes the work and transcribes its colophon or closing sentences.
