RIGHT?! La Mise en Abîme is an installation comprising two large, extremely precise and impeccably finished receptacles in which vast quantities of used oil are contained. Shaped like giant puddles, the sculptures with their shiny, and lacquer surfaces (thanks to the expressive properties of oil) reflect the surrounding, allowing the viewers to interact with the architecture of the church by being pulled into the reflection so that they, in turn, become part of the sculpture itself. The installation not only dispenses multiple visual thrills and mysteries but also offers a moment where sculpture creates another reading of space.
I also learned that Las Meninas by Diego Velázquez, and literary forms such as Shakespeare's use of the "play within a play" device are examples of la mise en abime technique. Ya don't say.
