4. Before the arrival of the 8th hour there are 3 more prominent stars in Canis Major. 2 of them are rising immediately before Canopus and 1 later than Sirius:

Furud ζ Canis Majoris 3.02 30° 02′ S 06h 18m 95.9 503.9
Mirzam β Canis Majoris 1.98 17° 56′ S 06h 20m 96.4 504.4
Canopus α Carinae −0.72 52° 40′ S 06h 21m 96.6 504.6
  ν Puppis 3.17 43° 12′ S 06h 35m 100.2 508.1
Sirius α Canis Majoris -1.46 16° 39′ S 06h 43m 102.2 510.2
  τ Puppis 2.94 50° 37′ S 06h 47m 103.2 511.2
Adara ε Canis Majoris 1.50 28° 54′ S 06h 57m 105.8 513.8

    Adara (105.8)  

The 'return of water' is possibly indicated by the S-formed arm like a toki in Ga2-1. At the bottom of the 'Sea' there is 'fire' and the rise of the Nile coincided with the hottest time of the year, the time named the 'dog days'. Much heat would then be dissipated by much rain.

The S-formed arm may be another sign than toki, an example of 'glyph-play'. It occurs also at the beginning of the Keiti text, e.g.:

Ea1-8 Ea1-16 Ea1-24 toki

I have earlier suggested there is a correspondence between ebb and flood on one hand and other pairs of contrasting phenomena - e.g. light and darkness, warmth and cold, firmness and flow - on the other. The cycle of ebb and flood can be used as a model for other cycles. The 'motors' behind the cycles of the year (2 of them like the number of cycles of ebb and flood in a day) could have been thought of as Canopus and Sirius. People 'sharp as knives' were, of course, aware that such ideas were only for those who were dull - there was a need to describe reality in a simplified way for the common people.

Judging from number 42 and the hakaturou sign - cfr at The Big Man - in glyph Ga2-11 the heliacal rise of Adara should mark a point of turning around.

"Adara, Adhara, Adard, Udara, and Udra are from Al 'Adhārā, the Virgins, applied to this star in connection with δ, η, and ο; perhaps from the Arabic story of Suhail.

It has also been designated Al Zara, with probably the same signification, although this form is erroneous." (Allen)

Adara is close to the beginning of the 8th hour and the note of Allen makes me decide to wait until later with discussing the significance of this star.

But we had better here mention what Allen has to say of the pair of stars close to Canopus:

"Furud is either from Al Furud, the Bright Single One [which ought to refer to Canopus I believe], or, perhaps by a transcriber's error, from Al Kurūd, the Apes, referring to the surrounding small stars with some of those of Columba; Ideler thought the latter derivation more probable. Al Sufi mentioned these as Al Agribah, the Ravens. ζ marks the toe of the right hind foot."

"Murzim, generally but less correctly Mirzam, and occasionally Mirza, is from Al Murzim, the Announcer², often combined by the Arabs with β Canis Minoris in the plural Al Mirzamāni, or as Al Mirzamā al Shi'rayain, the two Sirian Announcers; Ideler's idea of the applicability of this title being that this star announced the immediate rising of the still brighter Sirius.

² Literally the Roarer, and so another of the many words in the Arabic tongue for the lion, of which that people boasted of having four hundred.

Buttmann asserted that it also was Al Kalb, the Dog, running in front of Sirius, but this must have been from early times in the Desert. In our maps it marks the right fore foot of the Dog."
