7. Allen:

"Dubb, more generally Dubhe, the Bear, is the abbreviation of the Arabians' Thahr al Dubb al Akbar, the Back of the Greater Bear, Dubb being first found in the Alfonsine Tables.

Al Bīrūnī said that it was the Hindu Kratu, the Rishi or Sage.

Lockyer asserts that it was Āk, the Eye, i.e. the prominent one of the constellation, utilized in the alignment of the walls of the temple of Hathor of Denderah, and the orientation point of that structure perhaps before 5000 B.C.; at all events, before the Thigh became circumpolar, about 4000 B.C.

This was in the times of the Hor-she-shu, the worshipers of Horus, before the reign of Mena, when the star had a declination of over 64°, - now about 62° 24'.

Mena, Menes, or Min was the first historic king of Egypt, his date being variously given from 5867 B.C. to 3892 B.C., Flinders Petrie making it, from astronomical data, 4777 B.C.

And he finds two other temples also so oriented.

As typifying a goddess of Egypt, it was Bast Isis and Taurt Isis.

The Chinese know it as Tien Choo, Heaven's Pivot, and as Kow Ching."

The Back of Ursa Major indeed is beginning with Dubhe, 168 days beyond March 21:

Ga4-20 (104) Ga4-21 Ga4-22 Ga4-23 Ga4-24 Ga4-25
Dubhe (167.7)    Al Sharas (169.7), Zosma (170.2), Coxa (170.4)   Alula (171.5), Labrum (171.6) λ Crateris (172.6), ε Crateris (172.9), γ Crateris (173.0)
September 5 (248) 6 7 8 9 10
Ga4-26 Ga4-27 Ga5-1 Ga5-2 (*177) Ga5-3 (114)
κ Crateris (173.5)  ξ Hydrae (175.3) θ Crateris (176.0), ω Virginis (176.3) ι Crateris (176.5), ο Hydrae (177.1)  ζ Crateris, ξ Virginis (178.0), λ Muscae (178.1), ν Virginis (178.2)
September 11 12 13 (256) 14 15

Dots have been added to the 4 glyphs beyond manu kake in Ga4-21. The pair of mama glyphs have their 'tresses' upside down.

Allen:

"... ν, the northern of the two stars, is Alula borealis, from Al Kafzah al Ūla, the First Spring. ξ is Alula australis, the southern one in the combination, - Ulug Beg's Al Fikrah al Ūla ...

They [Talitha, Tania, and Alula] were interesting to the Arabs ... and were collectively designated Kafzah al Thibā', the Springs of the Gazelle, each pair marking one spring; the Gazelle being imagined from unformed stars since gathered up as Leo Minor, and the springing of the animal being due to its fear of the greater Lion's tail.

Ideler adopted this from Al Tizini and the Cufic globe at Dresden; while the Borgian globe shows a Gazelle and her Young in the same location. Kazwini, however, described the group as extending over the eyes, eyebrows, ears, and muzzle of the figure of our Ursa Major."

With September 16 comes the southern spring and Phekda (γ Ursae Majoris) is strategically positioned in day 260:

Ga5-4 (*179) Ga5-5 (116) Ga5-6 Ga5-7 (590)
μ Muscae (178.8), 93 Leonis (179.0), Denebola (179.3) Alaraph (179.6), Phekda, β Hydrae (180.3) η Crateris (180.9) π Virginis (182.0)
 Spring equinox (179 - 92 = 87) 17 (260) 18 12h = 182.6

"Phacd, and Phachd, Phad, Phaed, Phaecda, Phekda, and Phegda, are all from Al Faĥdh, the Thigh, where this star is located in the figure.

Al Bīrūnī said that it was Palastya, one of the Hindu Seven Sages.

The Chinese knew it as Ke Seuen Ke, and as Tien Ke, another Armillary Sphere." (Allen)

It is understandable it had to be one of the 10 Tahitian star-pillars:

1

Ana-mua, entrance pillar

Antares, α Scorpii

2

Ana-muri, rear pillar (at the foot of which was the place for tattooing)

Aldebaran, α Tauri

3

Ana-roto, middle pillar

Spica, α Virginis

4

Ana-tipu, upper-side-pillar (where the guards stood)

Dubhe, α Ursae Majoris

5

Ana-heu-heu-po, the pillar where debates were held

Alphard, α Hydrae

6

Ana-tahua-taata-metua-te-tupu-mavae, a pillar to stand by

Arcturus, α Bootis

7

Ana-tahua-vahine-o-toa-te-manava, pillar for elocution

Procyon, α Canis Minoris

8

Ana-varu, pillar to sit by

Betelgeuse, α Orionis

9

Ana-iva, pillar of exit

Phekda, γ Ursae Majoris

10

Ana-nia, pillar-to-fish-by

North Star, α Ursae Minoris

We should take the opportunity to list (in rising order) the Hindu Seven Sages:

Pulaha Merak
Kratu Dubhe
Pulastya Phecda
Atri Megrez
Angiras Alioth
Vashista Mizar
Bhrigu Alkaid
