Street Art is an expansive visual art movement created in public spaces, historically executed outside the context of traditional art venues. What began as a rebellious, underground graffiti subculture—characterized by tagging and claiming urban territory—has evolved into a globally recognized, highly diverse art form. Unlike traditional gallery art, Street Art is inherently ephemeral, often subject to weathering, removal by authorities, or being painted over by other artists.

The movement encompasses a wide range of practices, from freehand aerosol murals and intricate stencil work to wheatpasting, sticker bombing (slaps), and mosaic installations. Street Art challenges the boundaries of property, legality, and public discourse, turning city walls into open-air canvases. While early graffiti was primarily typographic and focused on the artist’s moniker, modern street art is highly illustrative, often tackling political, social, or environmental issues through subversion, dark humor, and pop-culture appropriation.

Manga (漫画) is a sophisticated Japanese sequential art form that evolved from 12th-century scrolls into a global cultural phenomenon. Unlike Western comics, Manga is a multi-generational medium with specific demographic classifications: Shonen (young males), Shojo (young females), Seinen (adult men), and Josei (adult women).

Technically, Manga is defined by its “cinematic” pacing. While Western comics often focus on action-to-action transitions, Manga frequently uses aspect-to-aspect transitions—lingering on a falling leaf or a background detail to establish mood or “Ma” (the interval of empty space). The style relies heavily on a specialized vocabulary of visual symbols, such as “sweat drops” for anxiety or “popping veins” for anger. For researchers, the core of Manga’s power lies in its Iconic Abstraction: characters are drawn with simplified, expressive features (large eyes, minimal noses) to allow the reader to project themselves onto the character more easily.

Classical Architecture refers to the highly structured, formalized building traditions derived from ancient Greece and Rome. It is a style dictated by sacred geometry, mathematical ratios, and a strict adherence to symmetry. Rather than merely being a historical era, Classical Architecture is a comprehensive design system that has been revived, adapted, and reinterpreted across millennia (through the Renaissance, Neoclassicism, and Beaux-Arts movements).

The cornerstone of the system is the Architectural Order. An Order dictates the specific shape, proportions, and decoration of the column, its base, its capital (the top of the column), and the entablature (the horizontal superstructure sitting on top). For students and researchers, the system is divided into five definitive canonical orders:

• Doric: The oldest, simplest, and sturdiest order, featuring a plain capital and no base (Greek Doric) or a simple base (Roman Doric).

• Ionic: Characterized by elegant, slender proportions and a capital decorated with spiral, scroll-like carvings called volutes.

• Corinthian: The most ornate style, featuring an elongated capital intricately carved with stylized acanthus leaves.

• Tuscan: A simplified, unfluted Roman adaptation of the Doric order.

• Composite: A rich Roman combination of the Ionic volutes and Corinthian acanthus leaves.

A core concept in Classical Architecture is entasis—the subtle, intentional swelling or curving of a column’s shaft. Classical architects discovered that perfectly straight columns appear to bow inward when viewed from a distance due to an optical illusion. Entasis corrects this, making the columns appear perfectly straight, rigid, and organically alive under the heavy weight they support.

Art Deco, short for Arts Décoratifs, was a dominant international design movement that epitomized luxury, glamour, exuberance, and faith in social and technological progress. Emerging in the interwar period, it completely rejected the organic, flowing, asymmetrical curves of Art Nouveau in favor of symmetry, linear clean lines, and geometric purity. It was not just a movement for fine art painters; it was an all-encompassing style that unified architecture, interior design, industrial design, fashion, and the visual arts into a single cohesive modern aesthetic.

For researchers and students, Art Deco must be understood as a clever synthesis of various avant-garde styles. It borrowed its fragmented geometric shapes from Cubism, its sense of speed and dynamism from Futurism, and its structural focus from the Bauhaus. Simultaneously, it drew deep inspiration from ancient, non-Western cultures. The global media frenzy surrounding the discovery of King Tutankhamun’s tomb in 1922 injected Egyptian, Mesopotamian, and Mesoamerican zig-zag and step-pyramid motifs directly into the Art Deco visual vocabulary.

The movement is generally divided into two stylistic phases:

• Zigzag Deco (1920s–Early 1930s): Highly lavish, colorful, and ornamental. It focused on surface decoration, expensive materials, and vertical geometric towers.

• Streamline Moderne (1930s): A stripped-back, more industrial evolution influenced by the Great Depression. It emphasized horizontal clean lines, curved aerodynamic corners, nautical elements, and a machine-age utility.

Modern Architecture (or Modernism) is a revolutionary movement that rejected historical ornament and traditional “styles” in favor of functionalism and structural honesty. It emerged from the idea that the form of a building should be determined solely by its function and its materials. This marked a total departure from the stone-masonry traditions of the past, embracing the industrial potential of the 20th century.

Key technical pillars include the use of steel frames, reinforced concrete, and large expanses of glass. The movement popularized the “open floor plan” by shifting the load-bearing weight from thick walls to internal columns (the Dom-Ino House concept). For students and researchers, Modernism is often divided into sub-movements like the International Style, Bauhaus, and Brutalism, all unified by the mantra: “Form follows function.

Abstract art represents a pivotal departure from “mimesis” (the imitation of visible reality). Instead of depicting recognizable objects from the physical world, it uses a formal language of shape, form, color, and line to create a composition that may exist with a degree of independence from visual references in the world.

For researchers and art centers, it is categorized into two main movements:

• Non-Objective / Non-Representational: Work that does not take anything from the real world as a starting point. It is pure form and color (e.g., Mondrian).

• Abstracted Reality: Work that begins with a real-world subject (like a figure or landscape) and simplifies or distorts it until the original source is nearly unrecognizable (e.g., early Kandinsky).

The movement evolved through various sub-genres, including Geometric Abstraction (logical and calculated) and Lyrical Abstraction (emotional and gestural). It challenged the viewer to “feel” the art rather than “identify” it.
