There's a translation of Marteau's summary of the numbers at:

Also, the Curtiss books have a comparative approach to the Majors (comparing several decks) with a focus on the numerology. Vol. 1 contains the first half the the majors, while Vol. 2 contains the 2nd half - so you'll need both volumes. I believe they are out of print but should be available at used book sites.
