Artist of the Day: Jaques-Louis David. The Oath of the Horatii. This painting epitomizes the neoclassical style of the 1800s, and shows the need for wartime virtue, not virtues of compassion and love. I apologize for my rather long absence, I was actually on tour with my choir in Washington, D.C. and have now returned home. Went to the national gallery and will be gushing on it forever.
