Primavera
Venus stands in an orange grove while the Graces dance and spring arrives at her right. The meadow holds hundreds of identifiable plants.

Venus stands in an orange grove while the Graces dance and spring arrives at her right. The meadow holds hundreds of identifiable plants.

Christ has just said one of them will betray him, and the shock rolls down the table. Leonardo's experimental paint began flaking in his lifetime.

Venus arrives on a scallop shell in a fall of roses, painted on canvas at a time when almost everyone still worked on panel.

God surges out of a red cloak full of angels, and Michelangelo leaves the fingers not quite touching. The gap does the work.

The marble block had been abandoned as flawed before Michelangelo took it, and he carved a boy who is watching Goliath, not beating him.

Plato and Aristotle argue at the center of a hall where Raphael gave the philosophers the faces of Leonardo, Michelangelo and Bramante.

Bernini staged the saint's own account of her vision as theater, lit from a window he hid above and watched by marble spectators in boxes.

The dead Christ lies across his mother's lap. Michelangelo was twenty-four, and signed the sash after hearing it credited to someone else.

Bernini was in his mid-twenties when he cut this, catching Daphne at the moment bark closes over her thigh and leaves push from her fingers.

Light follows Christ's pointing hand across a dim counting-room to Matthew, who gestures at himself in disbelief. The picture made Caravaggio famous overnight.

The earliest surviving painting built on a single vanishing point, worked out on a wall of Santa Maria Novella with Brunelleschi's help.

A naked boy in boots and a laurel hat rests one foot on Goliath's head, the first freestanding bronze nude since antiquity.

Bartholomew holds his own flayed skin, and the sagging face on it is Michelangelo's. The nudes offended enough critics that drapery was added later.

Judith and her maid hold Holofernes down together and work the blade through his throat. Artemisia painted it a decade after her rape trial.

Velázquez caught every wary line in the pope's face, and Innocent reportedly said it was troppo vero, too true. Francis Bacon reworked it for years.

When Duccio finished it in 1311 the whole of Siena walked it to the cathedral in procession, with the bells going the entire way.

Leonardo fixed Vitruvius's old problem by moving the centers, so that the navel governs the circle and the groin governs the square.

Three moments run in a single frame: the tax demanded, Peter pulling the coin from a fish, and Peter paying up at the right.

Titian woke Giorgione's sleeping Venus, brought her indoors, and had her look straight at us, probably to mark a wedding in Urbino.

Pliny ranked it above every other work of art, and when it came out of a Roman vineyard in 1506 Michelangelo hurried over to look.

A soldier, a nursing woman, and lightning over the town beyond. Nobody has explained what connects them, and Giorgione died young leaving few certain works.

Justinian carries the bread for the Eucharist in gold and purple, flanked by men who cast no shadow and stand on no ground.

Ghiberti gave twenty-seven years to these doors, and the name comes from Michelangelo, who is supposed to have said they were fit for paradise.

Eve throws back her head and howls while Adam hides his face, the bodies heavy and casting real shadows. Michelangelo came to study it.

Raphael left it unfinished when he died in 1520, and it was hung above his body while he lay in state.

Titian was barely thirty when Venice saw this go up over the Frari altar, the Virgin swept into a storm of red and blue.

Caravaggio's first attempt at the subject, turned down by the patron, before he threw out the angels and left one man, one horse and the light.

Bernini put the viewer where Goliath must be standing, so the sling is being wound up to throw straight past your head.

Two mourners sit with their backs turned to pull us in, and the angels overhead double over. Giotto frescoed it in the Arena Chapel at Padua.

Three weathered shepherds crowd in to look at the newborn, and when the triptych reached Florence from Bruges the local painters took note.

Christ is scourged in the middle distance while three men talk in the foreground, indifferent. Nobody has settled who they are or why.

The trees behind Christ turn from bare to leafing across the panel. In 1944 a British officer held his guns rather than shell the town.

Gabriel's greeting runs toward Mary in raised gold letters and she twists away from it, her thumb still caught in her book.

Life-size figures act out an initiation into the cult of Dionysus around three walls, buried by Vesuvius and dug out nearly intact.

Fra Angelico frescoed it at the top of the dormitory stairs, so the friars met it every time they climbed to their cells.

The kings arrive with a retinue of horses, hounds and a leopard, every surface tooled in gold for one of Florence's richest families.

The horns come from an old mistranslation of the Hebrew for rays of light. He was meant as one figure among many on a papal tomb.

No cross, no ground, no sky, just a spiral of mourners in acid pink and sea-green. Florentine Mannerism starts here.

Three laborers strain to lever the cross upright with Peter nailed to it upside down. No crowd, no glory, just heavy work in the dark.

The corner of the stone slab juts out of the picture so the body looks about to be laid down in the room with you.

Twelve meters of wall where the whole business of execution goes on at once, one thief still being hauled upright at the side.

Two moments in one field: Adam and Eve reaching for the fruit, then driven out, suddenly old. The serpent has a woman's torso.

Every proportion is wrong on purpose, and a single outsized column rises behind for no reason. Parmigianino died before finishing it.

An ostrich egg hangs from the vault and pulls every sightline down. Federico is shown from the left because a tournament took his right eye.

Torches and spears bristle against the sky, and at the still center Judas wraps Christ in his yellow cloak and meets his eye.

Where Cimabue and Duccio floated their Madonnas on gold, Giotto gave his weight, a real throne, and a body that presses through the cloth.

The saints share one continuous space instead of separate compartments, and the two kneeling physicians are the name-saints of the Medici who paid.

The table runs off on a steep diagonal into a smoky hall where servants clear plates and the lamp smoke thickens into angels.

Two women sit at either end of a sarcophagus full of water, and it is the naked one who stands for sacred love.

Myron's bronze is lost and this is a Roman marble copy, which is why a strut props the leg the original held up unaided.

No angel, no dove, no lily. Mary looks up from her book straight at us, because we are standing where Gabriel ought to be.

A real Roman boy dressed up as the wine god, heavy-lidded and slightly flushed, holding out a glass while the fruit beside him bruises.

Painted on a convex parade shield, so the head bulges toward you at the exact instant of the scream. A showpiece gift for the Medici.

The leaves are curling and worm-eaten and the fig has burst. Caravaggio painted the rot as carefully as the ripeness and called it enough.

Four and a half meters tall, the largest panel painted in its century, with six angels kneeling to steady a throne that seems to float.

An early work, and Mary's right arm reaches further than an arm can. Gabriel's wings were studied from a real bird.

The central panel of three, with the Florentine commander charging in a gold-and-scarlet hat on a horse turned like a carousel figure.

An angel drops steeply from the corner and its light is the only light in the tent. One of the first true night scenes in painting.

Asked where he found so beautiful a model, Raphael said he worked instead from a certain idea of beauty he carried in his head.

The little demons carved on the pedestal were taken for harpies and gave the picture its name. Del Sarto was called the faultless painter.

The holy family is tiny and the landscape does everything, which is the arrangement Poussin and Claude would build whole careers on.

The three kings are Medici, and the young man in the saffron cloak at the right, looking straight out at us, is Botticelli.

Six blind men go down one after another, and Bruegel painted their clouded eyes accurately enough for doctors to diagnose the conditions.

Michelangelo carved it for his own tomb, gave Nicodemus his own face, then took a hammer to it and broke off Christ's leg.

The Arno flood of 1966 stripped most of the paint off it, and the ruined cross became the emblem of the whole disaster.

Narcissus and his reflection close into a circle around a band of black water, and nothing else exists in the picture.

Raphael had just arrived in Florence and studied the Mona Lisa hard, then did the same pose in clear light instead of smoke.

Fruit already spotting toward rot, painted with the same attention as the boy holding it. An early statement of what Caravaggio intended.

Four prophets peer from arches under the throne holding scrolls that foretell the Virgin Birth, and the throne is angled to suggest depth.

This is the largest scene on the back of the Maesta, the Virgin fainting on one side and the crowd arguing on the other.

Cupid pulls back the sheet while two putti sharpen their arrows on a whetstone at the foot of the bed. Painted for the Duke of Mantua.

Two shepherds stop at a skull on a plinth and read the words carved there. Guercino used the motto first, decades before Poussin.

Her face is finished and breathing while the hair around it stays loose scribble, and nobody knows whether Leonardo considered it done.

Martin cuts his soldier's cloak in half with his sword to give a beggar the other part, dressed by Simone in courtly gold.

Moses wades into a heap of falling nudes to drive off the shepherds, the limbs knotted almost into abstraction under a harsh light.

A peasant looks up from his beans as though caught, spoon halfway to his mouth. Painted decades before Caravaggio's followers made a career of this.

Isaac is shouting under his father's hand and the ram has already arrived at the right. Caravaggio gives the scene no ceremony whatsoever.

Fra Angelico inherited a Gothic frame begun years earlier and filled it with deep sunlit space instead of gold, which is the whole story.

Two trees, a strip of ground, and a flock that stays to listen. Giotto tells the miracle as though it simply happened.

Giotto had watched Halley's Comet in 1301 and painted the Star of Bethlehem as a comet, apparently the first artist to do it.
