You'll study the ancient Greek hero archetype from two perspectives: the Epic, in the form of Homer's work, and the Lyric, in the form of Sappho's work, and examine the themes that run through them both, how both storytellers chose to present their characters and themes to you, and which of those themes we can easily see carried down to more recent stories today.
- Harvard University - HUM2.1x: The Ancient Greek Hero in 24 Hours (Hours 6-11): Signs of the Hero in Epic and Iconography - Professor Gregory Nagy: In the second five hours of the same course discussed above, the focus shifts away from Homer and Sappho and moves to how the Greek hero is displayed in art, iconography and other portrayals. The course continues to touch on Homer's heroes specifically, but instead of looking at written themes, this course focuses on the visual, including live performances and artwork.
- University of Liverpool - Psychology and Mental Health: Beyond Nature and Nurture - Professor Peter Kinderman: Much discussion of psychology focuses on whether people "were born with" certain traits, or "developed them" over time, but the reality is more complex. This course aims to go beyond that simple dichotomy and explore some of the current challenges in the mental health community, and how many researchers are looking for ways to improve our overall mental health at every age. You'll discuss and learn how clinical psychologists examine, learn from, and treat their patients, and get a greater understanding of how difficult it can be to diagnose and properly treat mental illnesses.
- Newcastle University - Hadrian's Wall: Life on the Roman Frontier - Professor Ian Haynes: In this part history, part archaeology course, you'll learn about life on the frontier of the Roman Empire, and what daily life was like for soldiers and civilians living on one of the most heavily fortified parts of the Roman Empire in its heyday.
