Regarding both their motifs and their style, the works of Magritte’s Période vache do not constitute a consistent ensemble but rather present themselves as a patchwork of different pseudo-styles borrowing more or less openly from other artists and drawing on the artist’s own earlier works. These elements are transformed into something comic, trivial, or grotesque by being blended with aspects of popular visual culture. With numerous art historical references Magritte ridicules traditional cultural values and aesthetic norms and distances himself from an art scene lusting for innovation. Contrary to his “classical” works, their cool, precise and realistic approach, and the conceptual consideration behind them, the works of Magritte’s Période vache strike us as colorful, two-dimensional, quickly painted, and radiating an astounding directness and spontaneity.
With his manifesto-like protest against all varieties of arrogance and reprimands in the arts, Magritte has become a model for the artist’s triumph over the workings of an art scene that seem to be more overpowering today than they ever were. (via)
