3. Gradually doubts were accumulating. A major obstacle was Metoro. If he saw a piece of land in this glyph type then surely it could not at the same time be a picture of a tree stem (or measuring staff). My esteem of Metoro has steadily grown and he certainly knew what he was talking about.

The Mayan te glyph - I have learnt - has no resemblance at all with henua:

A sun symbol is at left (like an eye with a pupil in the middle), while at right - I guess - is a picture of the sky from which what looks like  'rabbits teeth' are shining down, delivering their rays (illustrated like the 'feathers' in rongorongo) to earth below. This was a wooden club used for aggression, not a peaceful agricultural tool. (The picture is from Kelley, the words and imaginations are mine.)

Using a Mayan structure for sun 'residences' over the year the parallel to henua instead should be the time of maximum growth before the arrival of midsummer:

Here the so-called 'Rain God' (Kelley's term for the sun) is seen walking on land - footprints are used for describing the 'residence', his station in time, viz. 'land'. Footprints can only be created on the surface of earth, neither sea nor sky can do. The outline of the rectangular form at bottom may be the origin of the henua glyph type, I reasoned.

But I did not assume any contact between the Polynesian and the Mayan peoples - a piece of land will be drawn as a rectangular form irrespective of where on earth we look.
