Taking the Venus period or cycle of 584 days as a basis, he divided it by the twenty day signs of the Mayan month which gave him twenty-nine with a remainder of four. Hence every Venus cycle ended with a day-sign four days later than that preceding it. Then, dividing twenty by the four, he found five day signs were enough to serve as symbols for the terminations of Venus-cycles, and as the day signs were always combined with numerals from one to thirteen, and as thirteen divides 584 with a remainder of twelve, the terminal day of each Venus cycle was recognizable by its number being one less than the preceding one. Hence, as he pointed out, five times thirteen, or 65 Venus-cycles, must elapse before the same day name and number symbol could recur as an ending date to a Venus-period. Thus 65 Venus-cycles would equal two calendar Rounds of 52 years each or 104 years, and once in 104 years the Venus Count, the Calendar Count, and the Year Count would coincide to a day and hour. All of this dissertation on Nohul Voh’s astronomical knowledge and ability may appear to have no connection with my anxiety to find the Bridge of Light once more streaming across the chasm that barred escape from Mictolan. But, as a matter of fact, it had a most important bearing upon the matter. A man who nightly studied the heavens, who kept all the calendrical records, must, I believed, have observed when and how often and for how long a period the tell-tale flames from the great temple of the sun had flared against the sky. He could scarcely have avoided doing so, and his memory was so remarkable, that I felt sure that even if he had not recorded the dates of the occurrences, he could recall them. So, filled with my new scheme of establishing some definite facts regarding the incredible bridge, I hurried to the old fellow and explaining my ideas and theories, asked if he could give me information or data bearing on the subject.
