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 : FORMALISM
When 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").
A160 : Abstracts Geometrical constructs: "All over", soft constructs
with a certain sensitivity in materials or colour, reintroduced into the "hard" construct, whether square-based or not (S. Poliakoff, Malevitch, J.P Riopelle, Maurice Estève, M.H. Veira Da Silva, Barnett Newman, James Bishop, ...).
B axis : MATERIALITY
How does the materiality of what is shown come across?
(on a scale from more "immaterial" to more "real").
B210 : Materiality
in painting, but also with all other materials with the following possibilities: Structured with materials predominant
their thickness, composition or the way they are worked as structures (the way they are "built up") are here the most important aspect (Eugène Leroy, Bertrand Lavier, ...).
B220 : Materiality
in painting, but also with all other materials with the following possibilities: Structured predominance of volumes
particularly in sculpture and assemblages. Specially for "Minimal Art" and its derivatives (Sol Le Witt, Tony Smith, …).
C axis : INVOLVEMENT BODY/ MIND
With 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", ...).
C140 : towards the intellectual side/ the essence of things inward looking work chiefly oriented towards: fantasmagoric
fantasies of all types, be they sexual, social, religious or any other type, so long as there is formal mastery (from Georgia O'Keeffe to Annette Messager, through Clovis Trouille, ...).
D axis : COMMUNICATION
Does 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, ...).
D115 : via what is meant in various narrations or symbolisms whatever they may be
allegorical, metaphorical (J. Beuys' "materials", ...), analytical (Mario Merz's "Fibonacci series", or those of Robert Filliou, ...), critical (from Henri Cueco to Hans Haacke or Guillaume Bijl, ...).
D130 : via what is meaningful
based on the idea that work on what symbolizes forms an intentional message in itself (for example: Daniel Dezeuze's "Stretchers", etc., etc., ...). by variations in execution
seriality, multiplication (Claude Viallat, Niele Toroni, "figurines" by Antony Gormley, ...), accumulation or compression (J. Chamberlain, Arman, César, ...), subtleties and variability of the material (Rober Ryman's "Whites"; dissolutions of "matter / life" by Roman Opalka or by On Kawara; Gilberto Zorio, ...).
