At the time of Betelgeuze (*88) the Foot of the Centaur (Rigel Centaurus, Toliman, *221) would have (according to a simple extrapolation) risen heliacally in day 80 + (221 - 88) = 213 (1 August) and this was 8 days after Menkent (θ, *213) - which at the time of rongorongo was positioned at 14h (213.1) with Hamal at the other side of the sky.

... Strassmeier and Epping, in their Astronomishes aus Babylon, say that there its stars formed the third of the twenty-eight ecliptic constellations, - Arku-sha-rishu-ku, literally the Back of the Head of Ku, - which had been established along that great circle milleniums before our era; and Lenormant quotes, as an individual title from cuneiform inscriptions, Dil-kar, the Proclaimer of Dawn, that Jensen reads As-kar, and others Dil-gan, the Messenger of Light.

Brown associates it with Aloros, the first of the ten mythical kings of Akkad anterior to the Deluge, the duration of whose reigns proportionately coincided with the distances apart of the ten chief ecliptic stars beginning with Hamal, and he deduces from this kingly title the Assyrian Ailuv, and hence the Hebrew Ayil; the other stars corresponding to the other mythical kings being Alcyone, Aldebaran, Pollux, Regulus, Spica, Antares, Algenib, Deneb Algedi, and Scheat ...

At the time of Bharani (*41) Toliman (*221) would have risen heliacally in day 260 ("September 17) which was 180 (= 360 / 2) days later - although Zuben Elgenubi (*224) arrived 183 (= 366 /2) right ascension days later.

"Alpha's splendor [-0.01] naturally made it [Toliman] an object of worship on the Nile, and its first visible emergence from the sun's rays, in the morning at the autumnal equinox, has been connected by Lockyer with the orientation of at least nine temples in northern Egypt dating from 3800 to 2575 B.C., and of several in southern Egypt from 3700 B.C. onward.
