Poggio Helped Invent Italics Script
(p. 115) What Poggio accomplished, in collaboration with a few others, remains startling. They took Carolingian minuscule--a scribal innovation of the ninth-century court of Charlemagne--and transformed it into the script they used for copying manuscripts and writing letters. This script in turn served as the basis for the development of italics. They were then in effect the inventors of the script we still think of as at once the clearest, the simplest, and the most elegant written representation of our words. It is difficult to take in the full effect without seeing it for oneself, for example, in the manuscripts preserved in the Laurentian Library in Florence: the smooth bound volumes of vellum, still creamy white after more than five hundred years, (p. 116) contain page after page of perfectly beautiful script, almost magical in its regularity and fineness.
