This seemed astonishing to me, both in the number and the dominance of religious texts:
“According to one calculation, as many as 7.5 million copies of ‘major religious works’ were published in England between 1580 and 1639, in contrast to 1.6 million secular poems, plays and sonnets, while between 1580 and 1639 the religious writings of WIlliam Perikins ‘scored’ 188 editions compared with Shakespeare’s 97.” –from Ideas: A History of Thought and Invention, from Fire to Freud, by Peter Watson.
