Seattle Art Museum says that its 35-hour marathon concluding the Louvre's Roman art show will include gladiators, which sounds like a recipe for lameness that could reach Renaissance faire levels. It could be ironic-good. Or, if you're in the market for regular-good, there's the promise of simply being at the museum with Augustus and double-Elvis at 3:00 a.m.—and admission will be half off during the wee hours. (Seattle Art Museum, 1300 First Ave, 625-8900. Sat 10 am–Sun 9 pm, $20/$10 from 2–7 am.)
