As the sky gets dark, be prepared to enjoy the wonders of the night sky! Don't forget to dress warmly. Please check the weather forecast. For lighting, cover a flashlight in red cellophane (the darker the better). Bring along water to keep hydrated. Note: This outdoor event is weather-dependent and may be cancelled because of significant cloud cover or precipitation.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The Secrets of Runes,”** on the origins, development, and interpretation of the runic script, with Lilla Kopár, runologist and a professor of medieval literature and culture at Catholic University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-rune-secrets](https://events.ticketleap.com/tickets/profsandpints/nv-rune-secrets) .] The fame of runes outshines that of any other ancient script. They can be found not just on Viking Age rune stones, but on Bilbo’s door and as the Bluetooth logo on your cell phone. Runic script is commonly associated with magic, used by modern practitioners of neopaganism, and in recent decades has captured the imagination of filmmakers and video game designers. Yet most of us know little about the historical origins of runes and have no clue how to read or use them. Come to Crooked Run Fermentation in Sterling, Va., to get schooled on runic script with the help of Lilla Kopár, a veteran scholar of runes who has earned a following among Profs and Pints fans by giving fantastic talks on medieval monsters and Norse mythology. As someone who has carried out extensive field research on runes, published several articles on runic objects, and even appeared on the History Channel commenting on runes in America, she’s exceptionally qualified to introduce you to runology and the fascinating things that runes tell us. Dr Kopár will discuss the development of runic script from its humble origins on the borders of the Roman Empire in the first or second century CE, through its popularity in the Viking world, to its use and misuse in modern times. She’ll discuss how runes are a set of related alphabets that underwent changes over time and she’ll describe what inspired changes in this writing system and where and how runes were used in the medieval period. Her richly illustrated talk will highlight some of the most intriguing objects with runic inscriptions, from humble bone fragments to impressive rune stones, and offer insight into the scholarly methods of deciphering and interpreting runic inscriptions. We’ll also look at the function of the runic script from simple practical notes and memorial inscriptions to cipher-runes and magic. The most fun might be the in-class assignment, which will involve reading a few runic inscriptions and writing your name and other words in runes. (Doors: $17, or $15 with a student ID. Listed time is for doors. Talk starts 30 minutes later.)

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“The Hidden Cleopatra,”** an excavation through myth and slander to uncover the real Egyptian queen, with Jacquelyn Williamson, an Egyptologist and associate professor of archaeology and ancient art at George Mason University. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-hidden-cleopatra2](https://events.ticketleap.com/tickets/profsandpints/nv-hidden-cleopatra2) .] Depictions of Cleopatra are abundant in popular culture. A long list of painters have depicted her, Marilyn Monroe and Kim Kardashian have posed as her, and Vivien Leigh and Elizabeth Taylor famously portrayed her in Hollywood films. At the end of the day, however, what most of us think we know about Cleopatra is wrong, the product of the ancient Rome’s “fake news” and anti-Egypt propaganda. Learn about the real Cleopatra—and how our understanding of her came to be so distorted—with Professor Jacquelyn Williamson, scholar of women and power in ancient Egypt, teacher of courses on ancient Egyptian art and archaeology, and author of *Nefertiti’s Sun Temple: A New Cult Complex at Tell el-Amarna.* Dr. Williamson will walk us through how the first Roman emperor, Octavian, created the distorted image of Cleopatra as seductress that we know today as part of his political scheming to defeat his rival Antony and end the Roman Republic once and for all. Cleopatra has been the subject of debate and controversy ever since. William Shakespeare later relied on ancient Roman sources such as Horace and Plutarch in writing *Antony and Cleopatra*, and his play helped give rise to countless other works offering a distorted picture of her. Professor Williamson argues that “Cleopatra was a human being, like you and I,” and “deserves the dignity of being represented as accurately as possible.” Her efforts to set the record straight have met frustration, however—after being extensively interviewed for the recent Netflix historical docuseries Queen Cleopatra, she concluded that it, too, had missed the mark. You’ll gain a much deeper appreciation of the challenges of researching and accurately depicting the ancient past from Dr. Williamson, who also has taught at Harvard, Brandeis, and the University of California at Berkeley and is involved with an ongoing archaeological investigation of Queen Nefertiti’s sun temple.

[Profs and Pints Northern Virginia](https://www.profsandpints.com/washingtondc) presents: **“A Practical Guide to Social Change,”** a research-based look at how communities bring about reform and progress, with Marissa Robinson, founder of Real Health Impact LLC and an adjunct professor at George Washington University who teaches courses focused on public health leadership and social change. [Advance tickets: $13.50 plus sales tax and processing fees. Available at [https://events.ticketleap.com/tickets/profsandpints/nv-social-change](https://events.ticketleap.com/tickets/profsandpints/nv-social-change) .] Systems built on inequality rarely transform without deliberate pressure from the people most committed to justice, because progress takes coordination, conviction and willingness to change what has always been accepted. Real change starts when people choose to move together. Learn what research and experience say about how to make real social progress with Dr. Marissa Robinson, a public health practitioner who previously worked in federal agencies coordinating global and national public health initiatives focused on infectious diseases, HIV, and health equity. Among the key questions she’ll tackle: How do communities overcome barriers to create real change? When should evidence guide decisions and when does context matter more? She’ll discuss established frameworks for moving from intention to measurable progress and talk about the importance of building coalitions that actually work and of making decisions grounded in real data. You’ll learn about the importance of testing ideas on a small scale before going big, as well as how to use rapid feedback loops and continuous improvement cycles to refine approaches and scale what truly works. Dr. Robinson will share stories of ordinary people and communities who refused to accept the status quo and pushed through real barriers to achieve breakthrough results. She’ll talk about practical strategies, usable frameworks, and evidence-based examples that people can apply immediately in their own communities and organizations to support change that lasts. If you have dreamed about bringing about progress in your world, this talk will give you the clarity, direction, and confidence it takes to turn such dreams into reality.
