  1. Perspective and Printing Press - The First Information Revolutions Perspective

  2. Media • Pigments: minerals or organic. No organic synthetic colors until 19th century. • Fresco - pigment on plaster. • Tempera - pigment plus water or egg. • Linseed oil - 15th century. • Use of paint as wood preservative very recent. • First ready-mixed pigment and vehicle sold only in 19th century.

  3. Representational Styles • Conceptual - Elements sized or placed according to importance • Polydimensional - Objects viewed from vantage point that best shows features • Perspective • Not automatically seen as “natural” by other cultures • Children have to learn to interpret it

  13. Perspective • Vanishing point • Size reduction with distance • Conventions are cultural and learned.

  14. Development of perspective • Distance cues were known and used, but not systematically • Size - distance relations • Near objects overlap distant ones • Foreshortening • Convergence of parallels (pre-perspective examples are common, but lacked geometrical consistency.)

  15. The Book of Hours of the Duc du Barry, ca. 1400

  16. Size - distance relations inconsistent

  17. Inconsistent Viewpoints

  18. Convergence of parallels known but lack geometrical consistency

  20. The Funeral of Raymond Diocres (1408)

  21. Post-14th Century Realism

  22. A Very Modern Convention

  23. Development of perspective Disasters of 14th century led to graphic depiction of often unpleasant realities. Art climate was ripe for greater realism. Introduction of Ptolemy's Geographia about 1350 re-introduced projection techniques. Use of grids as drafting aids Camera obscura as aid in drawing

  24. Ptolemy’s Geographia

  25. The Camera Obscura

  26. Natural Pinhole Cameras

  27. Effects of perspective technique • Delight in new technical mastery (Tour de Force) • Discovery of power of close observation and attention to detail • Power of mathematics to explain nature • Power of simple principles to achieve great effects

  28. Tour de Force: Andrea Pozzo, 1600’s

  29. Tour de Force: Andrea Pozzo, 1600’s
