I had to reach down, far down into my (external) memory banks. There was something about Oedipus. I found it:

"The early rabbis, authours of Talmud, knew how, through skillful interpretation, to bring to light the 'Oedipus complex'. In the chapter on dream interpretation in the Tractate Brakhot of the Babylonian Talmud, it is said in the name of Rabbi Ishmael that if one dreams that he pours oil on an olive tree he is possessed by the desire for incestous relations with his mother ...

In the legend Oedipus' feet are swollen, in the pictures of Akhnaton the thighs are swollen. In folklore feet may stand for legs. In Greek, the word pous stands for both, in Egyptian, too, the word r-d (foot) stands also for leg. In the riddle that Oedipus solved concerning the creature that walks on four legs, on two, and on three (the staff being the third), the Greek word used in pous, and thus the name Oedipus could, and even preferably so, mean 'swollen legs' ..."

I read this many years ago in a book (Oedipus and Akhnaton) by Immanuel Velikovsky, an unorthodox but thinking man. Coordinating it with how Robert Graves in The White Goddess (equally knowing and unorthodox) describes the 'tanist' as the 2nd half of the year, and how the 1st and 2nd half (of a person's life) - young and old - compete for the single universal woman, I can by a long shot on the table for playing with ideas hit va'e pau.

Let us investigate, looking at facts. First I list all tagata glyphs in K (according to my glyph catalogue), the idea being to look for strange legs:

		the 1st Rei is at Ka2-10
Ka1-11	Ka2-9
				2nd Rei at Ka3-15
Ka2-11	Ka2-15	Ka2-17	Ka2-19
Ka4-4	Ka4-11	Ka4-16	Ka5-6	Ka5-11
				3rd Rei at Kb1-11
Kb4-4	Kb4-19	Kb5-103	Kb5-306

Excepting Ka1-11 all three glyphs with curious legs are located at the end of their groups (demarcated by Rei according to earlier results).

Ka1-11 possibly stands at a solstice (because of the vaha kai, at right), while Ka2-19 (note the ordinal number meaning sun-end) is the 5th among equals:

1			4
	Ka2-11	Ka2-12		Ka2-17	Ka2-18
2			5
	Ka2-13	Ka2-14		Ka2-19	Ka2-20
3			6
	Ka2-15	Ka2-16		Ka2-21	Ka2-22

Presumably he is standing at autumn equinox (or similar in the cycle), definitely at a 'tanist' position. His curious leg is not swollen, but his hand is. His strange leg probably is a precursor of the turned tail in Ka2-21. The 3rd tagata is 'waving goodbye', has number 15 ('noon') and is followed by a glyph with open ends (incorporating mauga). There is nothing wrong with his legs.

Ka5-11 has a position inside the main calendar, between the 2nd and 3rd Rei. He is the 4th member in a group with 13 glyphs, probably representing the turnover at 'noon' (also a turnover from side a to side b):

He has no swollen limb, but it looks as if he is unable to walk because he has no knees, and he has lost his left (from us seen) 'eye' together with his right hand - the arm is openended in a ghostly state. In Ka5-13 we recognize the curious 'legs' of Ka1-11:

Kb5-306 definitely is in a final part of the text, and presumably of events:

He has no swollen limb, but his left leg has no knee (like a staff), while his right leg is 'running'.

End of investigation. An enormous amount of work could be used up following the trail further into other rongorongo texts. A point has already been made, though, viz. that legs are involved at solstices.
