The name Rectoversion is built on the words "recto" (front) and "version". It is based on a French neologism which literally means "rotation of the front side (recto)" and corresponds to the visual artistic process that Michel De Caso followed to result in Rectoversion (in 1991).

A "rectoversed" painting is painted on its two sides which are first of all perforated right through. This artistic proposition asks numerous artistic and philosophic questions totally connected to our time. It notably calls into question the notion of the painting as "opened window" stemming especially from the Renaissance. Some artists take an interest in "Rectoversion" concept.

They group together recently around Michel De Caso into the movement rectoversion, from the year 10 to 10.000. All artists of this movement feel affinities with Rectoversion but each brings it his own sensibility, creativity and differences. Rectoversion does not function on the fusional and identity-based mode but opens towards another multiple and contradictory sphere.

There were some rare double-sided paintings during the history of art but the questioning of the front (recto), back (verso) and their reciprocal relationship was never pushed as far as in Rectoversion.
