| Classification : A170-A210-A180-B230-C130-C150-D110 The classification provides four or more codes placed on four axis (A - formalism, B - matériality, C - involvement body/mind, D - communication). These codes are positionning the artist in the art history.
A axis : FORMALISMWhen looking at the work, what type of formalisation first strikes the eye? Is it more abstract or more figurative, etc ? (on a scale from more "immaterial" to more "realist"). A170 : Abstracts mixed (between constructed and not constructed) from "Field Painting" to "Abstract Expressionism"; taking over the pictorial space by pushing forward the limits of "all over" (Mark Rothko, Jackson Pollock, J.P Riopelle, Joan Michell, Judith Reigl, …). A210 : Abstracts with signs The work as a whole remains abstract but includes (or consists entirely of): signs forming writing: writing without meaning the sign as an abstract shape placed in the composition of the pictorial space (R.Motherwell, Giuseppe Capogrossi, Christian Dotremont, Cy Twombly, ...). A180 : Abstracts not constructed / informal material / splodges from the most "Nuagist" to the most "Matter informalist" all types of play on the subtle properties of the painting medium and its coloured spaces (Zao Wou Ki, Sam Francis, Ben-Rath, …).
B axis : MATERIALITYHow does the materiality of what is shown come across? (on a scale from more "immaterial" to more "real"). B230 : Materiality in painting, but also with all other materials with the following possibilities: Structured structured combinations any combinations of lines, colours, matter or volumes of a more structured type (Michail Heizer, Anish Kapoor, Miguel Barceló, ...).
C axis : INVOLVEMENT BODY/ MINDWith what body:mind ratio does the artist enter into his work? Classify from the most "intellectual" (e.g."Concept Art"...) to the most "physical" (e.g. "Body Art", ...). C130 : towards the intellectual side/ the essence of things inward looking work chiefly oriented towards: l'introspective inner landscapes, emotions, feelings (Arpad Szenes, ...), serenity (Yves Klein's "Monochromes", ...), equilibrium ("mandalas" of Augustin Lesage or Adolf Wölfli, ...), memory (Boltenski "boxes", ...). C150 : between Where the material and corporal necessities of existence confront the multiple questions about its "essence" (from Munch's "Scream" to the Installations of Thomas Hirschhorn, from Karrel Appel's "Scream" to Francis Bacon, ...).
D axis : COMMUNICATIONDoes the artist have the deliberate intention to convey a message of any sort through his work? (classified from the most "mystical" to the most "worldly"). D110 : via what is meant with various spiritual or less marked religious influences (from Barnett Newman to Mark Rothko, from Roman Opalka to Arnulf Rainer, ...). |
