Crescentius, a patrician of Rome who, in the 10th century, sought to destroy the imperial power and restore the republic; on this he was defeated by Otho III., to whom he surrendered on promise of safety, but who hanged and beheaded him; Stephano, his widow, avenged this treachery by accepting Otho as her lover, and then poisoning him.
