Philosophical Idea Machine Infographic Grid

A 16:9 2x2 grid of luxury conceptual infographic posters visualizing four famous philosophies: [Stoicism, Existentialism, Utilitarianism, Nihilism]. Each quadrant depicts an intricate symbolic idea machine combining Renaissance memory theatres (wheels within wheels, concentric knowledge rings, symbolic emblems), Bauhaus elemental geometry, and Encyclopédie mechanical cross-sections with clockwork gears of dialectic and numbered parts. The medium resembles printed layers of translucent vellum with cryptic alchemical annotations, syllogisms structured as circuit diagrams, and historical constellation maps in sepia, parchment, and oxidized copper tones. Each panel features prominent typography with a large title: [CONCEPT NAME], subtitle: [ORIGIN / PHILOSOPHER / MAXIM], and microtext: [LOGICAL FORMULA / CITATION / LATIN TERM]. Meditative spacing, mandala-like symmetry, and soft illumination glowing as if lit from behind by candlelight. No trite symbols such as lightbulbs.
