If the dance accomplished in the three dimensions all the potential to carry out the objectives for which it was established (social identity, luck in hunting, fertility of the fields etc.), what could the image possibly add since it’s the least indicated medium to achieve the desired effect?
An episode from the Bible, even if it is part of a narrative and not figurative context, allows us to understand the ways of the transition from the context of real life on to the figurative one: “Moses said to Joshua:” Choose your men and go to fight Amalek. Tomorrow I shall stand straight on the top of the hill with the stick of God in my hand. “Joshua executed what Moses ordered him to do and went to fight Amalek, while Moses, Aaron, and Cur went up to the top of the hill. When Moses was raising his hands Israel was stronger, but when he dropped them, Amalek was stronger. Moses was tired of holding his hands so the other two, took a stone for him to sit down, while Aaron and Cur, from both sides, supported his hands. So his hands remained steady until sunset. Joshua defeated Amalek and his people with his sword (ex. 17.8-13). The episode from the Bible clearly describes the cosmological point we are interested in: in the first phase, the elder Moses, on the top of the hill, with very little strength, performs the cosmological gesture of the adoring, by doing this action he receives the divine force to be transferred to the army of Israel. But the action of Moses is conditioned by its mortal nature. In the second phase, Aaron and Cur make Moses sit on a stone (the support) and they help him to hold his arms until the end of the battle. It’s this action of “fixation” that transforms the gesture of Moses into a superhuman mechanism capable of producing an unlimited amount of energy. If in the first phase we are facing a meaningful gesture, which is part of a ritual act (the same act of cosmic mediation is performed by the Christian priest during the Mass), in the second phase the same gesture is transformed into a unique act with no end.
This occurs when an image is stuck to a support with a sacral function. By virtue of the eternal and unchangeable nature that archaic religions attribute to many supports (the surface of the rock, the walls of a cave or tomb or the vase containing the ashes of the deceased, etc.), an image is placed in the condition of producing its effects that last forever and without interruption. If a dance is danced effectively in a real time frame it will have measurable effects with the amount of energy actually produced, a dance represented will never stop producing unlimited energy that lasts forever due to the nature of the support on to which it has been represented. By virtue of its linguistic structure (closed code), the image can’t be mistaken and also lacks of the components that define a concrete life therefore it follows the same cosmological mechanisms that move the Universe. In this way a representation will be able to infallibly achieve the desired result and its effects will have a perpetual duration.
