Vitellio

, or Vitello, 13th century, flourished about 1254. We have of his a large “Treatise on Optics,” the best edition of which is that of 1572, fol. Vitello was the first optical writer of any consequence among the modern Europeans. He collected all that was given by Euclid, Archimedes, Ptolomy, and Alhazen; though his work is but of little use now.²
