We cannot be sure which book it was. For sake of illustration,
though, let us say the first volume, and which we know he had and
used, was a leather-bound, gold-and-marble-edged translation of a
French book called Complete Woman, by one Jacques du Boscq. Pub-
lished in London in 1639, it had been translated by a man identified
only as “N.N.”
hmm.. who knew NN was that old?
p.s. This is a quote from "The Professor and the Madman"
