... The ordinary year in the previous Roman calendar consisted of 12 months, for a total of 355 days. In addition, a 27-day intercalary month, the Mensis Intercalaris, was sometimes inserted between February and March. This intercalary month was formed by inserting 22 days after the first 23 or 24 days of February; the last five days of February, which counted down toward the start of March, became the last five days of Intercalaris. The net effect was to add 22 or 23 days to the year, forming an intercalary year of 377 or 378 days ...

Tegmine is ζ Cancri and the name seems to mean 'covering' - which would be appropriate if it was used only at leap-days. Al Tarf is β Cancri and its name indicates 'end'. Probably the creator of the glyph text meant this manu kake to be at a cardinal point and the 'bird' (the Sun) ought to climb beyond day 59 (or 60 in a leap year) ...

Atariki (the shadow king) at Betelgeuze was the beginning of the Egyptian X and in Ga2-29 we can therefore imagine him turned upside down. We could think of Procyon as his successor, rising up from Columba Noachi - his successor being the wife (ana tahua vahine) of toa te manava (the man at the belly).

... the oak had made trouble right from the start. When (in the second rune of the Kalevala) Sämpsä Pellervoinen had sowed trees, it was the oak alone that would not grow until four or five lovely maidens from the water, and a hero from the ocean, had cleared the ground with fire and planted an acorn in the ashes; and once it had started, the growth of the tree could not be stopped:

And the summit rose to heaven // And its leaves in air expanded, // In their course the clouds it hindered, // And the driving clouds impeded, // And it hid the shining sunlight, // And the gleaming of the moonlight.

Then the aged Väinömoinen, // Pondered deeply and reflected, // 'Is there none to fell the oak-tree, // And o'erthrow the tree majestic? // Sad is now the life of mortals, // And for fish to swim is dismal, // Since the air is void of sunlight, // And the gleaming of the moonlight.'

'One sought above in the sky, below in the lap of the earth', as we are informed by variants, but then Väinömoinen asked his divine mother for help.

Then a man arose from ocean // From the waves a hero started, // Not the hugest of the hugest, // Not the smallest of the smallest. // As a man's thumb was his stature; // Lofty as the span of woman.

The 'puny man from the ocean', whose 'hair reached down to his heels, the beard to his knees', announces, 'I have come to fell the oak tree / And to splinter it to fragments'.

And so he does. In several variants the oak is said to have fallen over the Northland River, so as to form the bridge into the abode of the dead. Holmberg (quoted by Lauri Honko, 'Finnen', Wb. Myth., p. 369) took the oak for the Milky Way ...
