Greece, Rome

Here is what Google Ngrams makes of a search for "Greece" and "Rome" in books in English from 1750 to 2010. Apparently, a long, slow decline, sharpest for Rome, as classical education is eroded. A little spike for Greece when the struggle for independence is on. As we might expect, many citations of Rome in the period just before, during, and after the American Revolution and the making of the Constitution.
