The Iconography of the Italian Renaissance, Explained

To look at an Italian Renaissance painting without iconographic literacy is to read a sentence whose verbs have been removed. The figures are still there. The composition is still beautiful. But the meaning — the argument the painting is making — is invisible.

A Renaissance painting was made, almost without exception, for a viewer who could read it. The patron, the painter, and the audience shared a common iconographic vocabulary — drawn from Christian scripture, from classical mythology, from medieval and humanist theology, and from a long tradition of pictorial convention — that allowed the image to mean specific things, in a specific theological or civic register, with no ambiguity. Five hundred years on, most modern viewers no longer share that vocabulary. The painting still works visually, but it has been deafened.

The reader below is not a complete iconographic dictionary — that volume runs to several thousand entries. It is the practical minimum required to read a typical Italian Renaissance composition with confidence.

Marian imagery is the foundation of Italian Renaissance painting's religious iconography. The Annunciation — the moment when the angel Gabriel announces to Mary that she will bear the son of God — is the most frequently painted single scene in the entire canon of Italian Renaissance art. It appears in versions by Fra Angelico, Leonardo (his earliest surviving work), Lorenzo Lotto, and dozens of other painters. The iconographic conventions are strict: Gabriel approaches from the left, holding a lily (emblem of purity); Mary is shown in a state of interrupted reading or prayer; the Holy Spirit, in the form of a dove, descends from above. A vase of lilies, an architectural setting suggesting a loggia or enclosed garden, and a beam of light entering from the upper left complete the standard composition.

The Virgin Mary appears in dozens of iconographic configurations: as the Madonna of Humility (seated on the ground, emphasising her humility before God); as the Madonna Enthroned (seated on a throne, emphasising her queenly dignity); as the Madonna of the Rosary; as the Pietà (holding the dead Christ); and as the Madonna Lactans (nursing the infant Christ). The colours of her garments are conventionalised: a red or crimson robe (the colour of her humanity, and of the blood of the Passion) beneath a blue mantle (the colour of heaven and of eternity).

The major saints of the Italian Renaissance are identifiable by their attributes — the objects or animals that, by pictorial convention, identify them in the absence of a written label. Saint Sebastian is bound to a column or tree and pierced by arrows. Saint Jerome is accompanied by a lion (from whom, according to legend, he removed a thorn) and shown either in the desert wilderness, in a scholar's cell with books and a skull, or beating his breast before a crucifix. Saint Catherine of Alexandria is identified by a wheel (the instrument of her failed martyrdom) and a sword; Saint Barbara by a tower. Saint Francis receives the stigmata — the wounds of Christ — in a rocky landscape. The Baptist holds a lamb, referencing his words: "Behold the Lamb of God."

Classical mythology enters Italian Renaissance painting most fully in the works commissioned by the Medici and other humanist patrons in Florence in the late fifteenth century. The mythological paintings of Botticelli — the Birth of Venus and the Primavera — are the canonical examples. Venus, goddess of love and beauty, is the central figure of both. In the Birth of Venus, she emerges from the sea as a fully formed adult woman, blown toward the shore by Zephyrus (the west wind) and received by one of the Horae (the goddess of the seasons). The scene recounts Hesiod's account of Venus's birth from the sea foam that gathered around the severed genitals of Uranus.

In the Primavera, Venus stands at the centre of an orange grove, flanked by the Three Graces (the goddesses of beauty, charm, and creativity) and by Mercury (identifiable by his winged hat and caduceus — the staff entwined by two serpents). To Venus's right, the nymph Chloris is seized by Zephyrus and transformed, as Flora, who scatters flowers before her. The composition is read as an allegory of spring and the generation of beauty, filtered through Neoplatonic philosophy.

Colour symbolism in Italian Renaissance painting is both conventional and flexible. Gold, used in background and in haloes, signifies divine presence and heavenly light. Blue, as noted, is the colour of the Virgin and of heaven. Red signifies both human passion and the blood of Christ — it is the colour of martyrs. Green signifies hope and the natural world. White signifies purity and virginity. These associations are not absolute — painters use colour expressively as well as symbolically — but they provide a first level of meaning in any composition.

The most important single piece of iconographic equipment for the modern viewer of Italian Renaissance painting is an awareness of what is not visible: the dedicatory inscription, the chapel context, the patron's personal history, the liturgical occasion for which the work was made. Renaissance paintings were not made for walls of museums; they were made for altars, for private oratories, for the lunettes of family chapels, for the studies of humanist scholars. Reading them in their original context — or reconstructing that context as carefully as possible — is the first responsibility of the serious viewer. The Atlas's individual painting pages attempt to provide that context for the canonical works; this essay provides the vocabulary to begin the reading.
