This glyph has a certain resemblance with Pb10-43. Explaining this glyph Metoro said: atua mata viri, something reminiscent of "Atua-metua mated with Riri-tuna-rei and produced the niu." Atua-mata-viri is similar to atua-metua-riri. Barthel believed that atua mata viri was mentioned in this line of glyphs:

Ga5-10	Ga5-11	Ga5-12	Ga5-13	Ga5-14	Ga5-15	Ga5-16

"Im Tafeltext Gr5 [Ga5] folgen die Zeichen 20 [right part of Ga5-10] und 79 [Ga5-11] als 'mata-viri' aufeinander. Es liegt nahe, das vorangehende Zeichen 290 [left part of Ga5-10] als 'atua' zu deuten. Zeichen 290 mit seinem massigen Leib und den fehlenden Beinen, könnte möglicherweise ein Idol aus Stein oder Holz darstellen und den Begriff der Gottheit symbolisieren."

Even if Barthel should be right, there is a possibility that Atua-mata-viri could be expressed by a single complex glyph (e.g. by the one we are here scrutinizing). I believe this to be more plausible than a rebus with more than one glyph. At least this seems to have been a possibility in the mind of Metoro. Could viri be expressed by the strange sitting position, with the leg as viri? And following Barthel perceive atua in the upper torso? But what about the prominent hand-sign?
