5. Snakes are undulating, they are like water flowing on a flat plain. If Algol stands at the end of the flat surface of 'water', then we ought to find the final of another such plain 182 days later - the Field (where 'land' is rising) has its opposite in the Abyss (where 'land' is sinking). 455 + 182 - 472 = 165:

			17
Gb8-11 (453)	Gb8-12	Gb8-13
Menkar (453.7)	Algol (454.9)

127
	*Ga5-17 (192)**	Ga5-18 (129)	Ga5-19	Ga5-20	Ga5-21
	Arich (192.5)

32
32	*Ga6-24 (229)**	Ga6-25 (166)	Ga6-26

Perhaps, therefore, Ga6-24 marks the end of the level 'land'. It is the 28th henua period. What star could be there?

*Menkar*	α Ceti	2.54	03º 54' N	03h 00m	45.7	453.7	453
*Algol*	β Persei	2.09	40º 46' N	03h 05m	46.9	454.9	454¼
*Algenib*	α Persei	1.79	49º 41' N	03h 21m	51.0	459.0	458¼
*Alcyone*	η Tauri	2.85	23º 57' N	03h 45m	57.1	465.1	464¼
?					229

229 / 364 * 1440 = 905.93m = 15h 6m, and 229 / 365¼ * 1440 = 902.83m = 15h 3m. There is only one suitable star:

Zuben Hakrabi

ν Librae

15h 04m

Zuben Hakrabi means the Scorpion's Claw and Libra was once the claws of Scorpio, a suitable place for the end of 'land'. Here summer Sun should be 'speared', I guess (i.e. north of the equator):

"During the Roman Republic and early empire eras, 60 scorpio per legion was the standard, or one for every centuria. The scorpio ... was a weapon of marksmanship capable of cutting down any foe within a distance of 100 meters." (Wikipedia)
