Typefaces became a very important thing during this time period. 

​

The standard handwritten typefaces for the time were slowly being phased out.  Prior to the birth of the printing press, the primary style of text was done by scribes in a calligraphic typeface, all being handwritten.  The different parts of the world each had their own styles of typefaces before the printing press.  During the Roman Empire a typeface called ‘Uncial’ was used which generally evoked the Celtic Round hand style typefaces.  During the time of Charlemagne, the typeface called ‘Carolingian lettering’ was used as a standard typeface for the Holy Roman Empire.
