'"I have joyfully done much evil in my life to those who have wished me evil, but if ever I did any evil to you two I repent, and I ask your forgiveness. The three mules which I strove to drive have torn me in pieces as your Father prophesied. The naked swords wait at the tent door to give me the death I gave to Gratian.

Tell Pertinax his Mother is in safety at Nicaea, and her monies are in charge of the Prefect at Antipolis. Make my remembrances to your Father and to your Mother, whose friendship was great gain to me. Give also to my little Picts and to the Winged Hats such messages as their thick heads can understand. I would have sent you three Legions this very day if all had gone aright. Do not forget me. We have worked together. Farewell! Farewell! Farewell!"
