2. Sadalsud means 'the Luckiest of the Lucky' and one might well wonder for what reason. Should I be forced to guess I suppose it means the King has survived into another cycle (by using a substitute, a stand-in, a scape-goat).

Allen:

"Sadalsuud - not Sund nor Saud, as frequently written - is from Al Sa'd al Su'ud, liberally translated the Luckiest of the Lucky, from its rising with the sun when the winter had passed and the season of gentle, continuous rain had begun.

In my astronomy book Sadalsud is translated as 'the Lucky Star of the Whole World', which makes more sense - the earth as a whole is lucky to receive the gentle rain which will revive her.

This title also belongs to the 22nd manzil, which included the star with ξ of Aquarius and c [also referred to as 46] of Capricornus."

According to Wikipedia the manzil Saad Al Saud comes later in the year than in 'February 10:

Takaure in Gb3-1 is probably standing at a cardinal point we know (see e.g. at The Big Man)

... Takaure in Ga4-2 comes 266 days after what evidently is the beginning of the 'fly season':

			180	84
Gb2-34	Gb2-35	Gb3-1 (292)			Ga4-1	Ga4-2 (86)
			266

and the position is 355 days beyond spring equinox (north of the equator), a number which refers (or alludes) to the day of winter solstice. Line b3 is without any sign of henua (see at Ana-mua):

... There were only 10 Tahitian star pillars and there are no henua pairs in the 11th glyph line on the G tablet and indeed not a single sign of henua in line b3. Otherwise henua is a common glyph type and can be found in nearly every glyph line:

	1	2	3	4	5	6	7	8
side a	x		x	x	x	x	x	x
side b	x	x		x	x	x	x	x

I believe the absence of henua ('land') in line b3 is due to the season of moko, where Sun disappears down into his hole in the west, where the dark watery winter half of the year (takaure) is beginning ...

By counting 13 days ahead from the time of solstice according to the Gregorian calendar we will reach day 368 or January 3:

The distance from the right ascension day of the star Sadalsud to the beginning of the manzil Saad al Saud seems to be 435 - 406 = 29 days.

In the Northern Hemisphere the coldest day on an average is January 19. From winter solstice (day 355) to day 365 + 19 = 384 (½ more than 13 * 29½) there are 29 days.
