I remembered Polyfemos, the famous cyclops whose only eye was pierced with a wooden spear by the solar character Odysseus. One eye could mean 'year' I thought, and 'cyclops' sounds a lot like 'cycle' + 'eye' (as in 'optics'). So I searched for information about Polyfemos in my library.

At first, though, I found another Polyfemos and started to read about him, because I believe that names are not arbitrary. E.g. the Iliad has 'I' at its start, whereas the Odyssey has 'O'; i.e. henua = light respectively vai = darkness, as I now imagine I can read it. And Homeros has 'H', also a heavy letter loaded with meaning.

If you now have read (via the hyperlink 'Iliad') what Jung, Heraclitus and Campbell have to say about these things, and if you are sensitive to such things, then you will have observed 'on one hand' (Iliad) and 'on the other hand' (Odyssey). In Tiahuanaco they also recognized fives ('give me five', Polynesian rima = Peruan Lima) both on the right hand and on the wrong hand, 180 / 5 = 36 days for each finger.

5 double-months in the light and 5 double-months in the darkness, and in between the 'years' there are times of death and birth, rejuvenation. Dipping into water means rebirth, baptizing. But you need to die first.
