For the first 8 glyphs in line Ca12 see previous page. Then there are 12 glyphs distributed in 4 subgroups:
Vaha kai in Ca12-17 is probably drawn to illustrate the last day of a 'great fortnight' (because February 17 is Gregorian day 365 + 31 + 17 = 413 = 14 * 29½) and therefore the first glyph in the Mamari text ought to coincide with Gregorian day 413 - 332 = 81 (March 22). At the 'corner of the house' the head of Tuna was buried and in Gregorian day 52 there is a coconut tree (niu). Ca12-23 corresponds to February 23 and in this triplet of glyphs we can count 122, 244, and 366 (with 122 * 3 as February 23):
February 23, we know, was anciently regarded as the last regular day of the calendar: ... a 27-day intercalary month, the Mensis Intercalaris, was sometimes inserted between February and March. This intercalary month was formed by inserting 22 days after the first 23 or 24 days of February ... Then follow 4 glyphs which perhaps are belonging at the beginning of line Ca13, although evidently they constitute a 5th and special kind of continuation of the previous vae group:
Counting from the 'coco-nut' suggests it was planted deliberately 314 ('π') days before February 24 in the next year:
March 22 (81) at Ca1-1 + 9 (March) + 16 (April) = 106 = 420 - 314. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
