8 * 7 = 57 and the glyph number is 570 (= 80 weeks). There is a great vertically oriented egg (or hole) in the very broad hanau. 285 is the number of days from the northern spring equinox to the end of the year and here the position is 365 + 285 = 570 days counted from January 1 the previous year.

580 = 365 + 215 = 20 * 29 = 285 + 295. North of the equator the heliacal rising of Minelauva (δ Virginis) was in day 80 + 195.1 = 275, at the beginning of October and close to 13h. South of the equator this time of the year coincided with the beginning of spring, 10 (October) - 6 = 4 (April) and 13h - 12h = 1h. 72 * 5 = 360:

The bottom of the figure at left in Cb7-26 (where 72 * 6 = 432) looks like an upside down vero and together with the vero with rising maro at left and the Sun held high in front it seems unavoidable to recognize the beginning of southern spring.

Spica (Ana-roto) ought to be in the text. Its heliacal rising (in rongorongo times) was at 202.7 which translates to Gregorian day 283 or October 10 in an ordinary year:


Cb8-6	Cb8-7 (570)	Cb8-8
October 10	11 (285)	12
Assarfa 3	4 (148)	5

We can here imagine not the nakshatra view but the time when Sun and star coincide, a suitable turn of events because roto carries this implication.

Roto

1. Inside. 2. Lagoon (off the coast, in the sea). 3. To press the juice out of a plant; taheta roto pua, stone vessel used for pressing the juice out of the pua plant, this vessel is also just called roto. Roto o niu, east wind. Vanaga.

1. Marsh, swamp, bog; roto nui, pond; roto iti, pool. 2. Inside, lining; o roto, interior, issue; ki roto, within, into, inside, among; mei roto o mea, issue; no roto mai o mea, maternal; vae no roto, drawers. Churchill.

Yet, let us search for the nakshatra star of Spica. 202.7 + ca 181 = ca 383.7 (close to 383½ = 13 * 29½), and 383.7 - 365¼ = 18.45, which position however does not coincide very well with any of my major listed stars.

The special nature of Spica possibly implies we should connect it with Alcor (80 Ursae Majoris):


Ga5-29 (140)	*Ga5-30 (204)**	Ga6-1
Spica, Alcor (202.7)		Heze (205.0)
October 10	11 (284)	12
Assarfa 3	4 (148)	5

... Proclus informs us that the fox star nibbles continuously at the thong of the yoke which holds together heaven and earth; German folklore adds that when the fox succeeds, the world will come to its end. This fox star is no other than Alcor, the small star g near zeta Ursae Majoris (in India Arundati, the common wife of the Seven Rishis, alpha-eta Ursae) ...
