  • What is the History of Art From Prehistory to Antiquity? - Part 3

    As this episode is being published on 9/11, let's all take a moment to appreciate our dauntless first responders, many of whom lost their lives fighting terrorism on that wretched day. Let the pulchritudinous unity following the attacks be a symbol for our nation and our world's unending struggle toward unity.
