(p. 32) Poggio possessed . . . [a] gift that set him apart from virtually all the other book-hunting humanists. He was a superbly well-trained scribe, with exceptionally fine handwriting, great powers of concentration, and a high degree of accuracy. It is difficult for us, at this distance, to take in the significance of such qualities: our technologies for producing transcriptions, facsimiles, and copies have almost entirely erased what was once an important personal achievement. That importance began to decline, though not at all precipitously, even in Poggio’s own lifetime, for by the 1430s a German entrepreneur, Johann Gutenberg, began experimenting with a new invention, movable type, which would revolutionize the reproduction and transmission of texts. By the century’s end printers, especially the great Aldus in Venice, would print Latin texts in a typeface whose clarity and elegance remain unrivalled after five centuries. That typeface was based on the beautiful handwriting of Poggio and his humanist friends. What Poggio did by hand to produce a single copy would soon be done mechanically to produce hundreds.
