One more point which will receive due attention in my monograph remains to be briefly noticed. As the symbol for air=east is situated to the right of the symbol for north, and the earth=west is to its left, it is clear that the central face is conceived as looking down from above upon the spectator. It is only when the stone is considered as placed face downward that the symbols assume their proper positions as regards the cardinal points. This reversal, which is the natural result of the association of the east and south with the right hand of the middle personage, suggests that the monolith may have been originally designed to be let into the flat or slanting ceiling of a building. As a parallel instance I will state that, some years ago, Señor Troncoso pointed out to me a fact he had noticed, namely, that the relative positions of the cardinal points on the Féjérvary chart were reversed and that it must have been intended to be looked at from underneath. Each of the element symbols is accompanied by four numerals placed in the angles of the squares, with one exception, where one numeral was obviously dislodged from its proper position by an encroaching emblematic ornament. The positions of these numerals and of their square enclosures are what recalled to my mind the opposite positions assumed by Ursa Major in its annual rotation around the axis of the heaven. Just as the central face primarily represented Polaris, so these squares figured the four contrapositions of the great constellation. The peculiar, almost cross-shaped figure resulting from the union and association of the symbols of the Centre, and of the Above, Below, Right, Left=Four Quarters, is a well-known conventional sign, generally known as a “nahui-ollin.” The accepted translation of this name is “four movements,” from olinia, verb=to move, and no name could be more appropriate for a symbol which, to my idea, like the swastika, actually represents the movement of the most conspicuous of septentrional constellations to four opposite places.
