This is a drawing series about September 11 that I did over the course of several years. Cerberus was the giant three headed dog that guarded the underworld in Greek mythology. I call it a proposition instead of a memorial because a proposition, as in a math proposition for example, asks for a response. A proposition is dynamic and expansive. A proposition is a living thing, it demands that we move forward through thought and creativity. A memorial is a tomb of frozen time, like a prehistoric insect trapped in amber, there is no where to go, no where to move.
