Ea7-16 Ea7-18 (235) Ea7-20
inoino te inoino te maitaki

Ea7-16 could perhaps mean a pair of half-years meeting at that time? But why rhombs? Because they stand for lunar double-months (59 nights), or? And the 'knobs'? One extra night?

We should not let imaginations lead us astray. Instead we must remember that we have a rather firm ground to stand upon, viz. Eb2-1:

*132
Ea7-20 (237) Eb2-1 (369)
a1 32 32 b1 42 368
a2 33 65 b2 27 395
a3 35 100 b3 38 433
a4 36 136 b4 42 475
a5 42 178 b5 35 510
a6 39 217 b6 36 546
a7 39 256 b7 42 588
a8 *34 290 b8 40 628
a9 36 326 sum 302
sum *326 sum total *628

The difference between 369 and 237 equals 132 and I have denoted this difference with an asterisk (*132) in order to make clear that it corresponds to the difference in right ascension days.

July 9 (190, *110) *132
