This is a good day to plan an evening “in.” So get yourself a cold drink and a bowl of popcorn, and tune in to your local PBS station for the first installment in a series called “The Power of Art.” Hosted by Simon Schama, professor of history and art history at Columbia University, the series will look at “8 artists, 8 stories, 8 masterpieces”—exploring in each episode how one artist and one work changed the way we look at art. In tonight’s episode, Schama explores the meaning and technique of Vincent van Gogh’s Wheatfield With Crows, and its impact on the course of modern art. Other artists in the series include Picasso, Caravaggio, Bernini, Rembrandt, David, Turner and Rothko. Check your local listings! And if you watch, remember to come back here and share your comments!
