Representation Vs Mediation

Representation assumes that there is some imitiation or mimesis of an original object/person/idea. This is a specific type of mediation, where the representation is what mediates the original object/person/idea. An example of this would be an object which is represented by a drawing which could then be represented by a painting or a sculpture etc (with each representation relying on imitation). In contrast, mediation is a much broader category which does not necessarily have to take the form of mimesis. In fact, I would argue that mediation could just as easily take on the opposite form (as a kind of abstraction, deviation, or negation of the original).
