The effects of this cultural revival were mostly limited to a small group of court "literati". According to John Contreni, "it had a spectacular effect on education and culture in Francia, a debatable effect on artistic endeavors, and an unmeasurable effect on what mattered most to the Carolingians, the moral regeneration of society". The secular and ecclesiastical leaders of the Carolingian Renaissance made efforts to write better Latin, to copy and preserve patristic and classical texts, and to develop a more legible, classicizing script, with clearly distinct capital and minuscule letters. (This was the Carolingian minuscule that Renaissance humanists took to be Roman and employed as humanist minuscule, from which has developed early modern Italic script.) They also applied rational ideas to social issues for the first time in centuries, providing a common language and writing style that enabled communication throughout most of Europe.
