"Duel de masques" (1888) by James Ensor is an oil on canvas that exemplifies the Belgian artist's fascination with carnival imagery and masked figures engaged in theatrical confrontation. The work employs Ensor's characteristic expressionistic style with vivid, acidic colors and distorted forms to create a sense of psychological tension and social commentary. The painting reflects Ensor's broader preoccupation with masks as symbols of deception, identity, and the absurdity of human society.
