Since I’m going to talk about reading diagonal lines in the Lenormand Grand Tableau, let’s assume for the moment that the title of this post is a colorful allusion to that rather than a) an aeronautical term for the angular deflection or “droop” of an airplane tow rope, b) a prenatal determinant of gender or c) a vulgar bit of urban slang. (See, you learned something already!)
The distance method of reading the Grand Tableau involves first reading the cards touching a Significator or topic card and then those cards radiating outward from that center, with a gradually shrinking degree of influence the farther away they get. This is done most commonly along the horizontal and vertical axes due to the left/right and above/below dualities of the GT, but – since there are eight cards touching a focus card placed near the center of the layout – there are also four chains of cards extending at 45° angles from the hub. In this method of interpretation, the diagonal cards are given weight equal to that of the axial cards, with those cards above the Significator showing aspects of the situation that the querent is obliged to accommodate, those cards below reflecting issues he or she has more control over, those cards to the left revealing influences that are fading in magnitude, and those cards to the right representing factors that are growing in importance. The cards fall loosely into four quadrants around the Significator that blend these qualities (See Lenormand – 36 Cards by Andy Boroveshengra for more detail.)
The cards that have a lateral, medial or right-angle orientation to the planes of the focus card support techniques like distance, intersection, mirroring (or reflecting) and knighting. The cards that are oblique to those planes are normally limited to distance and mirroring. I’m not aware of anyone knighting “on the diagonal,” but there is a special case where intersection can play a part.
That situation occurs when two non-adjacent cards chosen for intersection occupy the same row or column in the spread. There is no right-angle relationship between the cards from which to generate the vertical and horizontal lines that link the two positions by their meeting. However, by extending lines from those starting positions along the diagonal paths on the same side of the row or column and in a converging direction, those lines will eventually intersect in a triangular fashion. Thus, by doing this on both sides of the row or column, instead of forming the typical “rectangular box” from the two original cards and the vertical and horizontal points of intersection, you create a diamond pattern with the four diagonal lines. The array is read in exactly the same manner as the rectangle, with all of the considerations mentioned above.
