Benjamin - Authenticity and Historical Testimony

"The authenticity of a thing is the quintessence of all that is transmissible in it from its origin on, ranging from its physical duration to the historical testimony relating to it. Since the historical testimony is founded on the physical duration, the former, too, is jeopardized by reproduction, in which the physical duration plays no part. And what is really jeopardized when the historical testimony is affected is the authenticity of the object."
