"υ¹-υ⁷ mark another series of seven stars [in addition to those 9 which are designed with the letter τ] called in Bayer's text Beemim and Theemim. This last, used by Bode and now in current use, is perhaps the Arabic Al Tau'amān and the Jews' Tĕōmīm, the Twins, from the pairs υ¹, υ², and υ³, υ⁴.

Grotius thought it derived either from the foregoing or from an Arabic term for two medicinal roots; but Ideler's suggestion that it is from the Hebrew Bamma'yim, In the Water, would seem more reasonable, although we have but few star-names from Judaea, and he intimated that it might be a distorted form of Al Thalīm, the Ostrich.

The Almagest of 1515 has Beemun; and the Standard Dictionary, The.e'.nim." (Allen)

... Kaus Borealis, the Northern (part of the) Bow, was Al Tizini's Rā'i al Na'āïm, the Keeper of the Na'ams, the uncertainty as to the meaning of which has already been noticed; but Kazwini evidently understood by it Ostriches, for in his list it is, with the stars μ, Al Thalimain, plainly meaning these desert birds.

With the same stars it may have been the Akkadian Anu-ni-tum, said to have been associated with the great goddess Istar ...

A desert is a barren piece of land and opposite to the teeming life in water:

"teem ... †bring forth OE.; be prolific, abound with ... f. Germ. *taumaz TEAM." (English Etymology)

"team ... A. †child-bearing, †offspring ... brood ... B. set of draught animals ... number of people in concerted action ... D. (dial. after ON. taumr) chain for yoking draught animals ... ON. taumr bridle, rein ... f. *tauχ- draw, rel. to L. dūcere ..." (English Etymology)

We can imagine a connection with Tammuz. Likewise can we see the time of plowing the fertile earth with a team of yoked draught animals. And the number of people in concerted action (a team) reminds me of what happened at the end of a great cycle:

... When it was evident that the years lay ready to burst into life, everyone took hold of them, so that once more would start forth - once again - another (period of) fifty-two years ...

... 1. Hanga Te Pau, the landing site of Ira and his band of explorers, is the natural anchorage for those approaching Vinapu by sea. The remarkable stone fronts of the ahu of Vinapu are all facing the sea. The explorers landed at Hanga Te Pau during the month 'Maro', that is, June ...

2. The cult place of Vinapu is located between the fifth and sixth segment of the dream voyage of Hau Maka. These segments, named 'Te Kioe Uri' (inland from Vinapu) and 'Te Piringa Aniva' (near Hanga Pau Kura) flank Vinapu from both the west and the east. The decoded meaning of the names 'the dark rat' (i.e., the island king as the recipient of gifts) and 'the gathering place of the island population' (for the purpose of presenting the island king with gifts) links them with the month 'Maro', which is June. Thus the last month of the Easter Island year is twice connected with Vinapu. Also, June is the month of summer solstice [a mistake: south of the equator it is winter solstice], which again points to the possibility that the Vinapu complex was used for astronomical purposes ...

"Baily's edition of Ulug Beg's catalogue gives this [α Centauri] as Rigil Kentaurus, from Al Rijl al Kentaurus, the Centaur's Foot; describing it as on the toe of the right front hoof, and Bayer so illustrated it ..."

"Algebar and Elgebar are seen in poetry for this star [β Orionis] but it univerally is known as Rigel, from Rijl Jauzah al Yusrā, the left foot of the Jauzah ...

Possibly its 'marine' character came from its location at the end of the River, and from its being given in the various editions of the Syntaxis and in the Alfonsine Tables as common to both constellations ..."

Thus Rigel, at the left foot of Orion, could mark the final of the River Eridanus while the right foot of Centaurus, Rigil Kentaurus or Toliman, could mark some other final.

In the Babylonian zodiac the Mad Dog (Centaurus) has his right foot in front, whereas the True Shepherd of Anu (Orion) has his left foot in front:
