POETS RIOT WHEN CAMPUS IS THROWN OUT OF RHYTHM By Mike Harden THE COLUMBUS DISPATCH At a reading by former U.S. poet laureate Billy Collins last week at Ohio Dominican University, I wasn't surprised to see a Columbus police officer on hand to thwart potential violence. Tensions have been high lately between neo-formalists and free versers, and well-placed sources in the poetry community feared that a reading might provide a flash point for simmering hostilities. I was glad I had taken my notebook. I needed it to chronicle the savage mayhem that has come to be called ''The Night of the Long Stanzas'': Columbus police and the Ohio National Guard patrolled the university Friday after a night of rioting between rival poetry gangs resulted in three minor injuries and a dozen arrests. Eleven of those in custody were being held for disorderly conduct. The 12th was apprehended for using eight syllables in the second line of a haiku. Of those injured, the most seriously hurt was an Obetz woman who suffered a concussion after being struck in the head with a copy of John Milton's Samson Agonistes. ''She was just an innocent bystander who happened to be in the wrong place at the wrong time,'' Columbus Police Sgt. Holger Upvall said. ''We think she might be a T.S. Eliot enthusiast who simply got caught in the crossfire. We tried to talk to her in the ER, and she wasn't making much sense -- which would seem to indicate a strong connection with Eliot's work.'' The trouble started, Upvall said, when tailgating revelers got out of hand. ''You know how it is,'' he said. ''You get a few neoclassicists doing that beer-bong thing with dry sherry. They haven't had any watercress. They can get pretty rowdy. ''A couple of the blank versers started talking trash about Coleridge. One thing led to another. We got matters calmed down until some hotheaded formalist accused a blank verser of an unnatural act with Edgar Guest. Well, that did it. ''Then someone ran over the mailbox of the school's professor of Renaissance poetry. Witnesses told us the culprit was driving a dark-green Volvo with a 'Save the Earth' bumper sticker. We stopped 137 vehicles fitting that description but didn't make any arrests.'' Police tried to form a perimeter around the Birkenstock store and the health-food co-op but were too late to save either from looters, Upvall said. Firefighters stood by helplessly as rioters -- their faces lighted by the flames of arson fires -- carried case after case of tofu from the health co-op, leaving a trail of anguish and alfalfa sprouts in their wake. Neo-formalists kidnapped a Rod McKuen fan, then holed up in the Birkenstock store, where they hurled sandals at confused police officers attempting to free the hostage. A police negotiator persuaded the neo-formalists to release the hostage by promising to read a list of demands. Essentially, they are asking for a return to more oblique and obscure poetry. ''How can we be expected to teach poetry,'' an unidentified neo-formalist noted, ''if there is nothing confusing about it? We need hidden meanings, confounding allusions, cryptic inner dialogues -- all those things that drive students crazy.'' Billy Collins, whom the neo-formalists consider far too ''accessible," was whisked out a back door of Erskine Hall and hastily driven to the airport. Collins' lawyer, quoting the poet, said his client had no intention of returning to Columbus ''in this or any other lifetime.'' Mike Harden is a Dispatch columnist. mharden@dispatch.com
