Commentary
The Eros definition evolved from the original Thanatos definition, which then gave rise to the synthesis of the Macro definition. This cooping of a destructive term by artists is thought to have originated in late 1970s New York as a way to express both the similarities and differences between illegal image saturation and legal violent destruction. There is an irony at play. It is the irony of color, beauty, and creation being illegal and persecuted while mass murder, hatred, and destruction are often sanctioned and rewarded. The Eros definition is, so to speak, a serious joke.
