The reason for including Hb5-18 among the tahana in the catalogue here becomes more understandable. It should, though, be noted that without the close proximity to the more obvious tahana (which are rare in the rongorongo texts) I would presumably not have included it as a glyph with a tahana sign (where the head of tagata normally is). Ea4-28 is another glyph with such a sign, and without the experience from Hb5-18 I would not have seen it as tahana:

Ea4-28

Wíth 3 glyphs per day Hb5-25 is the last in the triplet for day 290. Hb5-19 - a bird looking back - stands at the end of day 288 (= 8 * 36). These are signs which indicate sun has reached to the end of his rule. Another such sign is Hb5-9, which is quite similar to the end glyph in the 24th and last period in a calendar in E:

Hb5-9	Eb6-19

In Hb5-11 a tagata (completed season) has a pau sign at bottom right, possibly alluding to Hanga Te Pau, and at right a sun 'fish' is rising. Vaha mea (in Hb5-16) is 'the red opening' and illustrates the arrival of a new 'dawn'. Day 288 (Hb5-17--19) apparently is the day when one year is ending and the next is beginning - in Hb45-17 there is a gap between tagata at left and the 'feathered' mauga ('mountain on fire') at right - which (we can guess) illustrates how darkness (mauga) is changed into light ('feathers').

288 = 12 * 24 = 16 * 18 = 9 * 32, and the last expression could allude to 9 'months' during which the newborn sun will come and deliver the growth necessary for life on the island. On the other hand, 288 is also equal to 8 * 36, and in this capacity we may have met the number earlier.

In Hb5-17 mauga has 5 feathers, in Hb5-18 there are 6. Possibly tagata at left in Hb5-17 refers to the end of the regular year, and in Hb5-18 tagata with the curious tahana head' (without 'eyes') might indicate the dark period before a new 'light' has been 'born'. Perhaps the top of tahana glyphs refers to the 'open gap' between one year and the next.

Haati in Hb5-15 has an inverted hipu sign at its top end. The old solar year is leaving and a new fire will soon be pushing upwards. An inverted hipu presumably is the later stage of pau (cfr Hb5-11). We can compare with Gb6-18:
