Argillan (in Jerusalem Delivered).
A haughty, turbulent knight, born on the banks of the Trent. Accusing Godfrey and his brother of having murdered Rinaldo, he induced the Latians to revolt. The revolt spread to the Swiss and English, but Godfrey succeeded in restoring order. Argillan was arrested, but made his escape, and was slain in battle by Solyman. (Books viii. ix.)
