Both the Rider-Waite deck and the Thoth deck are largely inspired by the Golden Dawn tarot curriculum, especially in the case of the numbered minor arcana. Thus, if you're interesting in reconciling the divinatory meanings for the numbered minor arcana between the two decks, it's worth checking out the divinatory meanings for the numbered minors in the GD's manuscript "Book T".
