How many words did Vasari use in 1550 and in 1568 in his Vite? He certainly might have known more words than he used. How many times did he use certain words? How many types of a word did he include; which words, how did he use them, and why, in what context? Yet, why would anyone be interested in how many are the words Giorgio Vasari might have known or used? My sole intention is to provide some thoughts for further research in the studies of art history, using outcomes and tools from Italian historical linguistics and corpus linguistics.
