### Goals of this class

Using mathematical principles (with an emphasis on geometry),

• analyze artwork

• create artwork

### Themes of this class

• dimension - how can artwork be described in terms of its dimensionality?

• validity - when does mathematical analysis have a valid claim in interpreting art? when is it misused?

• Syllabus

• Web site

### Proportion in portraiture

• The length of a man's outspread arms is equal to his height.

• …. from the bottom of the chin to the top of the head is one eighth of his height; ….The greatest width of the shoulders contains in itself the fourth part of man. ... The whole hand will be the tenth part of the man.

• Source: The Notebooks of Leonardo da Vinci, Vol. 1 (of a 2 vol. set in paperback) pp. 182-3, Dover, ISBN 0-486-22572-0.

### Proportion in portraiture

Other sites:

• The figure-drawing lab

• Marc Frantz’s material on perspective and proportion

### Practice

• Use this work (Self-Portrait, Between the Clock and the Bed) by Edvard Munch to test some of the proportion rules.

### Questions

• What concerns would drive an artist to use these proportions?

• What concerns would drive an artist to break these proportions?

• Consider Edvard Munch’s The Scream

### For next class….

• Bring a ruler and graph paper.

• Start the homework (due next Monday) on the web site.
