Si forte in alienas manus oberraverit hec peregrina epistola incertis ventis dimissa, sed Deo commendata, precamur ut ei reddatur cui soli destinata, nec preripiat quisquam non sibi parata.

(Translation: If by chance this wandering epistle, sent forth to the uncertain winds but commended to God, wanders into alien hands, I beg that it be returned to her to whom alone it was sent, nor should anyone steal things not written for him.) From: The prologue to the Liber Confortatorius of Goscelin of St. Bertin (born between 1030 and 1040).
