One technique often used by tarot readers when analyzing a spread is that of preponderance – determining whether there is an abundance (or conversely, an absence) of any fundamental aspect of interpretation. This approach can show where too much (or not enough) attention is being paid to certain particulars of the matter, possibly to the detriment of others. This method of synthesis was borrowed from astrology, and provides a high-level overview of the reading before diving into the details.
Factors typically considered are element, suit, number and rank (trumps, courts or minors). This is often done on the fly, in a somewhat cursory manner as experience is gained; consequently, some subtleties of the evaluation might be missed. I thought it would be useful to have a color-coded reference table that organizes the various types of cards according to their active or passive affinities. I used Aleister Crowley’s court card titles (but not his trumps), William Lilly’s “temperaments” and Joseph Maxwell’s theory of odd and even numbers in compiling these lists.
