Central Problem

How do different compositional formats—circular, elliptical, and square—determine the visual dynamics of artworks, and what structural relationships are established between the centric and eccentric systems within each format?

Main Thesis

The tondo imposes absolute centricity that elevates the subject toward religious transcendence and detaches it from terrestrial gravitational coordinates; the ellipse introduces a bipolar tension between two foci; the square balances centric symmetry with the eccentric grid of verticals and horizontals, creating a state of atemporal stability. In every format, the interaction between the centric and eccentric systems generates the visual and symbolic substance of the work.

Historical Context

The chapter situates itself within the context of visual composition theory developed by Gestalt psychology and applied to the figurative arts. Arnheim analyzes the Florentine Renaissance tradition of the tondo (15th-16th century), the Mannerist and Baroque use of the ellipse, and the modern rediscovery of the square format in Constructivism and geometric abstraction of the 20th century. The discourse moves between medieval cosmology (T-O maps), 18th-century visionary architecture (Boullée), Christian symbolism, and contemporary painting.

Key Concepts

Concept	Definition	Related to
Centricity	Compositional system governed by a central fulcrum that confers stability and absolute predominance	Arnheim, radial symmetry
Eccentricity	System of gravitational coordinates (vertical/horizontal) that anchors composition to terrestrial space	Arnheim, spatial grid
Microtheme	Small concentrated version of the main subject placed at the center of the work	Arnheim, condensed symbolism
Spatial anisotropy	Perceptual asymmetry that causes overestimation of vertical distances compared to horizontal ones	Arnheim, visual weight
Internal tondo	Circular form within the composition that functions as an autonomous center with its own visual weight	Arnheim, halo, disc
Ovato tondo	Approximate construction of the ellipse using two overlapping circles, typical of Renaissance workshops	Arnheim, bipolarity

Authors Comparison

Theme	Albers	Mondrian
Format	Centric square	Decentered square
Dominant system	Centricity with gravitational tension	Pure eccentricity, weightless
Color	Full range of hues and brightness	Only three pure primaries
Center	Clearly indicated by square deviation	Avoided, uniformly distributed
Weight	Compression below, expansion above	Homogeneous, no hierarchy
Frame	One of the squares in the series	Forms continuing beneath the border

Influences & Connections

• Predecessors: Arnheim ← influenced by ← Gestalt, Burckhardt, Warburg
• Contemporaries: Arnheim ↔ dialogue with ↔ Cassirer (via Warburg)
• Applications: Arnheim → applied to → Renaissance tondi, Baroque ellipses, Modern abstraction
• Followers: Albers, Mondrian → exemplify → centric vs eccentric systems

Summary Formulas

• Arnheim on the tondo: The circular format imposes absolute centricity that elevates the subject toward transcendence; the border functions as a circular horizon embracing the contents.
• Arnheim on the ellipse: The ellipse introduces bipolar tension between two foci, representing the transition from geocentric to heliocentric cosmology.
• Arnheim on the square: The square balances centric symmetry with the eccentric grid, creating atemporal stability where both systems coexist without conflict.

Notable Quotes

“The circular format has an essentially ideal character, accepting only subjects of quietude and ideal beauty.” — Burckhardt

“The ellipse represented a turning point for human thought… its two poles reproposed the characteristics of the universe: they controlled the motions of the cosmos.” — Warburg

“The tondo contains, as it were, the entire philosophy of the round image, so clearly as to make it possible for every free gaze to understand what this most beautiful and most difficult format signifies for representation.” — Burckhardt
