#20th century

• Abstractionism — An avant-garde art movement that emerged at the beginning of the 20th century, characterized by the refusal to faithfully represent visible reality and the elimination of figurative forms. It places the pure language of geometric shapes, lines, textures, and colors at the center of the creative act, viewing them as autonomous vehicles for conveying emotional states or complex metaphysical concepts.
• Antonescian — Belonging, referring, or specific to the military dictatorship, ideology, or period when Romania was led by Marshal Ion Antonescu (1940–1944). In a historiographical and political sense, the term describes structural administrative elements, wartime decisions, legislative measures, or social realities during the Antonescu regime, characterized by authoritarianism, strict censorship, and geopolitical alignment with the Axis Powers.
• Auden — A proper surname of Anglo-Saxon origin; it refers fundamentally to Wystan Hugh Auden (W. H. Auden, 1907–1973), one of the most prominent and influential poets, playwrights, and essayists of the 20th century. His work is noted for its stylistic and technical achievement, engagement with politics, morals, love, and religion, and its immense impact on modern English poetry.
• Audiberti — A proper surname of French origin; it refers specifically to Jacques Audiberti (1899–1965), a French writer, playwright, poet, and journalist. His highly original work is characterized by exuberant, baroque language and vivid fantasy, exploring primordial life forces, making him a key precursor of avant-garde theater.
