“ Artaxerxes was easily persuaded, and, with the assistance of the guards, kills his brother. Artabanus seeing his treachery succeed according to his heart's desire, now boasts before all his sons that the time was come for his advancement to the kingdom, and forthwith comes to Artaxerxes with his sword drawn, and wounds him. The king not being much hurt, bravely defends himself, and kills Artabanus upon the place. ”
