The document summarizes the legend of the Lethe River from Greek mythology. It tells how in 136 BC, Roman soldiers led by Junius Brutus arrived in Viana do Castelo, Portugal and mistook the local River Lima for the River Lethe, which was said to make those who drank from it forget their memories. Despite their captain drinking from the river without ill effect, the soldiers refused to cross it out of fear of forgetting their homes and families. The legend will be reenacted by students on the banks of the River Lima while dressed as Roman soldiers.
