ABSTRACT
The association here between planet-god and facies is quite clear: the facies is a mask behind which the planet acts. This figure is not a decan-god in its
own right.45 This point is made clearer, perhaps, when one is reminded
that the fact that the Primer lapidario o f Alfonso X el Sabio is a textbook for magicians. The dark man with an axe is an image that is to be carved
on a specific stone in order to bring the powers o f the planet Mars to
bear.46
