When the Erie Canal opened in 1825, it revolutionized American travel and transportation, but its inspiration came from Europe’s earlier canal networks. In this course, we will trace the development of French, British, and Irish canals in the 17th and 18th centuries. We will follow the story into the 19th century as we turn to American canals, especially in New York and Pennsylvania. Along the way, we will explore how canals reflect the politics and aspirations of different nations and why they still matter for global shipping today. Whether we are drawn to engineering marvels, the people who built them, or the pleasure of drifting along a canal or hiking a towpath, we will deepen our appreciation of canals’ importance and beauty.

In this course, we will trace the evolution of literature specifically written for children - from its earliest forms to the modern era. We will begin with the oral traditions that underpin all storytelling, then follow the shift toward published works created specifically with young readers in mind. We will survey key moments and turning points that shaped the growth of children’s literature as a distinct field. We will conclude by analyzing how a well-known children’s literature has evolved over time.

In this course, we will explore how a tiny nation – Portugal – played an outsized role in world history. We will examine Portugal’s fifteenth and sixteenth century maritime expansion (once called the “Discoveries”), as well as its central role in the transatlantic trade in enslaved people. We will trace how Portugal, once a fringe region of the Roman Empire, emerged as the only independent kingdom on the Iberian Peninsula as Castile grew into Spain. We will follow Portugal’s rise as a global power, with outposts stretching from Brazil to Japan, and then its decline as rival empires overtook it – culminating in twentieth century poverty under Europe’s longest dictatorship. Finally, we will consider how this past continues to shape Portuguese identity and culture in the decades since a revolution ushered in democracy. As we survey Portugal’s landscapes, art and architecture, and food, we will see why record numbers of Americans are now visiting the country.

Coffee will provide a lively lens on major past and present issues, including climate change, social life, health, global North–South differences, social and economic justice, tourism, and slavery. We will begin “from the ground up,” tracing coffee from planting and processing through shipping and, ultimately, the beverage in our cups - part of nearly two billion cups consumed daily worldwide. We will explore coffee’s global history and its shift from an elite drink to an everyday staple. Drawing on current research, we will examine coffee and health, as well as practical questions such as how more income might reach farmers and how coffee production might adapt to a changing climate. The instructor will share firsthand experiences from coffee farms around the world, discuss a range of brewing methods, and demonstrate how coffee is brewed. Sessions will be interactive, with time for questions throughout.

As America celebrates 250 years of independence, this course will examine the indispensable founder, George Washington.  We will explore Washington's life and political leadership as well as his work as a farmer, entrepreneur, and architect.  We will also review the groundbreaking work of the Mount Vernon Ladies' Association (MVLA) which has owned and managed George Washington's Mount Vernon since 1858. In that year, an intrepid group of women (who had no right to vote or own property) came together to save George Washington's home, after both the Federal Government and Commonwealth of Virginia had refused to help. MVLA formation marked the birth of the historic preservation movement.

What makes an Oriental rug so captivating—its elegant design, intricate patterns, or the mystery of its origins? In this richly illustrated course, we will discover the stories woven into these remarkable textiles. We will travel through the history and artistry of rug and carpet weaving, a tradition rooted in Asia and North Africa, with examples dating back to the 4th century BCE. Using stunning visuals and expert insights, we will explore major carpet-making cultures and regions including Anatolia, Iran, Transcaucasia, North Africa, and Central Asia. We will learn to recognize defining features of Oriental rugs: weaving traditions (nomadic and settled), key historical periods (from the Early Modern era through the nineteenth-century), purposes (from prayer to decoration), and production contexts (from royal courts to bustling markets). We will also be introduced to basic methods for identifying weave structures and deepen our appreciation of these remarkable works of art.
