into the visual principle of uniform but segmented succession. 
Escapement introduced the reciprocal reversing action of the 
hands in rotating a spindle forward and backward. The meeting 
in the mechanical clock of this ancient extension of hand 
movement with the forward rotary motion of the wheel was, in 
effect, the translation of hands into feet, and feet into hands. 
Perhaps no more difficult technological extension of 
interinvolved bodily appendages could be found. The source of 
the energy of the clock was thus separated from the hands, or 
the source of information, by technological translation. 
Escapement as a translation of one kind of wheel space into 
uniform and visual space is thus a direct anticipation of the 
infinitesimal calculus that translates any kind of space or 
movement into a uniform, continuous, and visual space.
