Euclides, Signed (2 results)

Extrait. Condition: Gut. pp. 213-226, 17 fig. From the library of Prof. Wolfgang Haase, long-time editor of ANRW and the International Journal of the Classical Tradition (IJCT). - With author's dedication to Meyer Reinhold. - Author's name and title handwritten on cover, a bit dog-eared, otherwise good and very clean. - From the text: The library of the Duke of Urbino, Federigo da Montefeltro, now in the Vatican, contained a manuscript of Euclids Optics (Vat. Urb. Lat. 1329), De aspectuum diversitate, which was written in Rome (1458) for Francesco da Borgo Sansepolcro, papal secretary. The richly adorned opening page includes a framed picture of a city street (fig. 1), whose presentation recalls the architectural perspective of many a Quattrocento painting (fig. 2). Just below the manuscript illumination is a simple diagram showing four rays emanating and diverging from a single point. Illustrating Euclids first postulate - Nothing that is looked at is seen in its entirety at one time - the picture is accompanied by a text that states Let us suppose that those visual rays which move out from the eye proceed in straight lines and create intervals between them. The visual cone described by Euclid is resurrected in Albertis visual pyramid. Sprache: Englisch Gewicht in Gramm: 550.
