For four days in March, you can immerse yourself in the culture of the Middle Ages at the annual spring lecture series hosted by UNM’s Institute for Medieval Studies. This year’s program, “Presenting the Medieval World,” includes six lectures and a concert — all free and open to the public — focusing on how the material culture of medieval Europe has been collected, preserved, and displayed throughout history. The keynote lecture by Metropolitan Museum of Art curator Barbara Drake Boehm, “Towering Presence: The Role of the Cloisters,” is at 7:15 p.m. on Monday, March 25. She discusses the Met’s celebrated Cloisters Collection, which includes such marvels as the Mérode Altarpiece and the famous Unicorn Tapestries. Subsequent lectures take place Tuesday through Thursday, March 26 to 28, and are presented by leading researchers from prestigious institutions — including Marina Rustow of Princeton and Harvard’s Anna-Marie Eze. Using period instruments, UNM’s Early Music Ensemble presents a selection of vocal and instrumental medieval compositions at 5:15 p.m. on Thursday, March 28. For a complete listing of events, visit ims.unm.edu or call the institute at 505-277-2252. All events take place in Room 101 of Woodward Hall (300 Yale Blvd. NE, on the UNM campus) in Albuquerque.
