“Delivery of the Keys to St. Peter” by Pietro Perugino is an early example of one point perspective. Note how the lines converge in the central building.
“The Last Supper” by Leonardo DaVinci not only illustrates one point perspective but also shows how this perspective can be used to draw the eye to the focal point.
Two point perspective is just that — all lines converging on two separate points. “Paris Street: Rainy Day” by Gustave Caillebotte incorporates both one and two point perspective.
There are other ways of creating both perspective and depth. Foreshortening is another approach, but one that requires considerable skill. “The Lamentation of Christ” by Andrea Mantegna is an early, imperfect, attempt at foreshortening.
Albrecht Durer came up with a grid method to help artists translate 3D objects into 2D representations. This method is one that can be used by quilters as well.
Dr. Ortiz did touch on some other artistic principles — the use of positive and negative space, the difference between shape and form, implying mass through the use of highlight and shadow, tenebrism, and chiaroscuro.
"Figure of a Woman" by Paul Colin illustrates the importance of light and shadow, evident here in the human face.
He also talked about the visual interaction of colors, which is not always what one might expect. This interaction is apparent when colors are placed next to one another, overlapping, or one on top of the other.
|In the painting, "Le Chahut," Seurat used tiny dots of complementary colors next to each other, expecting them to create a vibrancy. The effect, however, was a muddying of the hues, creating the overall impression that looks much like brown.|
Professor Ortiz concluded his presentation with critiques of several quilts brought in by members.
The program ended with an invitation to the members to focus on incorporating at least one of these principles in a quilt to be shown at a meeting next May. The gauntlet has been thrown down, Ladies!
