Professor John Haldon, author of The Byzantine Wars, will be speaking at Georgetown University in Washington, D.C. on Thursday, February 16th on the topic, The Secret of 'Liquid Fire': An Early Medieval Terror Weapon. It sounds like it should be an interesting talk, if you live nearby. It will be held in the ICC Auditorium at 5:30 p.m. For more information, call (202) 339-6940. I understood Professor Haldon to be on the faculty at England's University of Birmingham, but the notice lists his affiliation as Princeton University, so perhaps he's on a visiting professorship, or has recently emigrated to the U.S.
