Leonardo's Words

There are three branches of perspective: the first deals with the reasons of the diminution of objects as they recede from the eye; the second contains the way in which colours vary as they recede; the third and last is concerned with the explanation of how the objects ought to be less finished in proportion as they are remote. — Leonardo da Vinci, Treatise on Painting
Among the great things which are found among us, the existence of Nothing is the greatest. Its province is in time, and its sway extends over the past and the future and all things. — Leonardo da Vinci, Notebooks
Shadow is the obstruction of light. It appears to me that shadows are of supreme importance in perspective, because without them opaque and solid bodies will be ill-defined. — Leonardo da Vinci, Notebooks

Key Concepts

  • Three Branches of Perspective: Linear perspective (geometric diminution), perspective of disappearance (loss of detail with distance), and aerial perspective (color shift through atmosphere).
  • Unity of Light: A single, consistent light source governing all shadows, reflections, and color temperatures within a composition.
  • Sfumato as Atmospheric Tool: Not merely a blending technique but a systematic rendering of how atmosphere intervenes between the eye and distant objects.
  • The Dissolution of Boundaries: Leonardo's ultimate insight — in nature, there are no hard edges; everything merges into everything else through light, air, and distance.

Works Analyzed

Arno Valley Landscape

1473 · Uffizi Gallery, Florence

Leonardo's earliest dated drawing — already showing an intuitive understanding of aerial perspective, with distant hills fading into atmospheric haze while foreground details remain sharp.

The Annunciation

c. 1472–1475 · Uffizi Gallery, Florence

Early application of linear perspective in the architectural setting, combined with a receding landscape that experiments with color gradation over distance.

The Last Supper

1495–1498 · Santa Maria delle Grazie, Milan

The supreme demonstration of single-point perspective extending the architectural space of the refectory — the vanishing point at Christ's right temple unifying real and painted space.

Mona Lisa (Background)

c. 1503–1519 · Musée du Louvre, Paris

The background demonstrates all three branches of perspective simultaneously — the winding road (linear), the diminishing detail of distant bridges (disappearance), and the blue-green haze of far mountains (aerial).

Virgin of the Rocks

c. 1483–1486 · Musée du Louvre, Paris

The grotto setting as a laboratory for light behavior — demonstrating how illumination enters, reflects, and scatters within an enclosed rocky space.

Deluge Drawings

c. 1515–1518 · Royal Collection, Windsor

Leonardo's late apocalyptic visions — where atmospheric perspective is pushed to its extreme, showing the dissolution of all solid form into swirling water, wind, and atmospheric chaos.

Open Questions

  1. Did Leonardo develop a mathematical formula for the blueing of distant objects, or was his aerial perspective purely observational?
  2. How much of the Mona Lisa background's atmospheric quality is original vs. the result of darkened varnish?
  3. Were the Deluge drawings intended as illustrations for a planned treatise, or purely personal meditations?
  4. To what extent did Leonardo's understanding of optics (the camera obscura, the eye) directly influence his painting technique?
  5. Was the single vanishing point in the Last Supper a deliberate theological statement or a purely formal choice?
