Final paragraph of the prologue to the Liber Experimentarius, naming Bernard as the 'faithful translator from the Arabic.' The dots represent the usual method of obtaining one's key number or figure. A. random number of dots were quickly 'cast' in four parallel lines and the number of dots in each line was counted: if a line had an even number 2 dots were left; if an odd number, one dot.. The resulting pattern was one of 16 possible combinations (2212, 1121,1221 etc.) each of which carried its own meaning, or (depending on the form of geomancy favoured) led on to the next stage.

Sixteen possible Questions in lettered boxes, each question occurring twice. By finding his question and noting the two letters, the inquirer proceeds to tables (not shown) headed by 2-letter combinations. From information in this table, he is referred to a sector of one of 13 circular tables (frames 10-15) where he finds the name of a 'judge' or 'king'. Under each of these judges are listed 9 'answers' and his key number locates the solution to his enquiry.
