4. Dubhe has rectascension 11h 01m which is equal to 661m. If there is a correspondence between the 472 days in G and the 472 rectascension minutes from The Dog Star to The Mad Dog, then we ought to reduce 661 with 403 in order to find the glyph of Ana-tipu. 661 - 403 = 258, but I cannot perceive anything which obviously connects Gb2-2 to Ursa Major:
The great cardinal point between Gb1-26 and Gb2-1 should rather represent Ana-tipu than Gb2-2. And it would have been nice if Dubhe had a rectascension number just 1 minute lower. I decide to adjust it accordingly. With 26,000 years for a full cycle of precession 1m corresponds to 26,000 / (24 * 60) = ca 18 years and 1h to 18 * 60 = ca 1080 years. If the G text was created e.g. 288 years ago, then the values I am using for rectascension ought to be adjusted downwards with 288 / 18 = 16 minutes. 258 - 16 = 242:
But the difference between the rectascension values for the stars remains constant (more or less). I will therefore not speculate too much about the absolute rectascension values and instead continue to use those which are current today. Furthermore, if we assume another observation time than sunrise this will also change the numbers. Let us, however, update our map with Ana-tipu:
If this structure was created 1080 years ago, then Ana-tipu would have had a rectascension number of 10h. And it would as always arrive 256m after Sirius:
It could have announced the end of the Sun year south of the equator. And 986 - 660 = 326m later (i.e. 12 / 24 * 326 = 163 days later) Ana-mua would once again rise in the east announcing the arrival of a new summer. Maybe, therefore, the text of G describes only 236 days (with each glyph corresponding to 1m). |
