Does anyone know how far the Hoy Book Test goes back? I've been told that it goes back to Al Koran and even before that. I'm trying to complete a bibliography.
Although Al Koran did have at least two book tests in his repertoire, I've never heard of his having used the Hoy test.
It's worth noting that very little of what's been published as Koran's is actually his. That's also true (but to a lesser degree) with David Hoy.
Having said that, although the principle on which the Hoy book test is based goes back at least as far as the late 1700s, its book test application does appear to have originated with Hoy.
This conclusion is supported by the fact that the method does not appear in the rapacious C. L. Board's tome on book tests, Mainly Mental
volume two, which was published in 1950, thirteen years prior to Hoy's Bold and Subtle Methods of Dr. Faust
. This strongly suggests that the idea was not established at that time, and adds credibility to the attribution to David Hoy.
