"The worthy and skilful Messer Piero di Pergolotti of Verona is repairing to your magnificent Lordships, who for a good while has been at Pesaro, where he practised surgery, conducting himself with propriety and diligence, so that the lords of that place and myself feel much obliged to him, and consider ourselves bound to promote his knowledge by providing him with the means of study. He earnestly desires to enter into your establishment of the Sapienza, where he hopes to do credit to this recommendation, as well as to advance his own honour and advantage. And knowing how much I am devoted to your Magnificences, he has had recourse to me, hoping through me to effect his wish. I, therefore, in consideration of his capacity, science, and worth, pray that on my account you will consider him fully recommended, and will grant him admission into the Sapienza, whereby your Magnificences will greatly gratify me, to whom I ever commend myself. From Durante, the 2nd of May, 1440. "GUIDANTONIO, COUNT OF MONTEFELTRO, URBINO, AND DURANTE." "Mighty and potent Lords, most honoured Fathers, "There is in your Sapienza one Messer Zucha da Cagli, my intimate friend, who, as I am informed, is very able in civil rights, and who, for his advancement in reputation and skill, wishes to have a lectureship, either the one read after the first doctors come forth in the morning, or that in the afternoon an hour before the ordinary doctors enter. I hereby pray your magnificent Lordships, that the said Messer Zucha be at my sight recommended to you, and whatever honour or benefit your Lordships grant him I shall consider as bestowed on myself, and shall remain constantly grateful. From Cagli, the 24th of December, 1441. "GUIDANTONIO, COUNT OF MONTEFELTRO, URBINO, AND DURANTE."
