William R. Shepherd, The life of Poggio Bracciolini (1837)
“ I have received information that my most intimate friend, the dear associate of my studies, Poggio, the papal secretary, is detained in captivity by the magnificent lord and excellent captain Niccolò Piccinino. Believe me this intelligence is very painful to my feelings—but the concern which I experience is much alleviated by the opinion which I have long entertained of your humanity, and which induces me to hope that I shall not make a request to you in vain.—I beg and beseech you therefore, my lord, to use all diligence to effect the liberation of one whom you know to be most dear to me. ”
