Barely a century ago, it was widely accepted that Troy was a mythical city. It wasn’t, of course, and neither was Urkesh, the Hurrian capital known to the modern world principally from a passing Old Testament reference. Last year, archaeologists Giorgio Buccellati and Marilyn Kelly-Buccellati finally pinpointed the 4,000-year-old city at present-day Tell Mozan, Syria, in part by tracing two bronze lions once smuggled out of the area. In their slide-illustrated Smithsonian Associates lecture, “Ancient Syro-Mesopotamian City Found,” the L.A.-based husband-and-wife team will discuss what they discovered in excavations last summer, including a major temple complex and the remains of a structure that may have been the royal palace of this once-wealthy metropolis. At 6 p.m. at the Ripley Center Lecture Hall, 1100 Jefferson Dr. SW. $16. For reservations call (202) 357-3030. (MJ)
