I think that we can use the fundamental structure dividing the cosmos into three vertically separated parts, as in the Mayan 'Nunnery'. They probably would agree on Easter Island. In view of this discussion being about the week, and not the month which 13 + 7 + 9 = 29 in the 'Nunnery' seems to indicate, I propose we continue our discussion with summing up to 7 instead:

above earth	2
on earth	3
below earth	2

This cosmos would then have 3 kings, one for each level. Such a king could be indicated with a splendid bird, a bird not necessarily high up physically, but high up in the hierarchy. The king below the earth must physically seen be down below and not high up. These three kings ought to be:

above earth	Sun
on earth	Jupiter
below earth	Saturn
