Excerpt: When I first began to collect materials for the writing of the life of Poggio Bracciolini, I was much indebted to the kindness of my late friends Mr. Roscoe and Mr. William Clarke, who liberally allowed me the free use of the scarce books which they possessed, illustrative of the revival of letters in the fourteenth and fifteenth centuries. From various passages which occur in some of these works, I was convinced that there existed in the public libraries of the city of Florence several manuscripts, from which much information might be gathered respecting the history of the scholar, to whose early exertions for the promotion of sound learning I wished to do justice. In consequence of this persuasion, I felt a strong desire to visit the Tuscan capital, for the purpose of copying and[vi] analyzing such documents, suitable to my purpose, as I might there discover. But my professional engagements not allowing me to be absent from home for the requisite length of time, I was obliged, however reluctantly, to give up this project as impracticable, and to proceed in my task with the aid of such printed books as were accessible to me.
