Landscape with Saint Philip baptising the eunuch (Princeton University Art Museum): Acts' roadside baptism — the Ethiopian courtier's chariot halted at the desert water, belief made passage — in the last manner's pale light: the œuvre's final sacred-road subject, at Princeton since the twentieth century; the late Claude teaching in a university gallery, as the late Claude does best.

A capriccio of an Italianate harbour at sunset: the port theme in the final years' private-market form — towers, shipping and the low sun composed at liberty, the formula's last domestic statements while the great Virgilian machines occupied the easel's centre.

The picture

Oil on canvas, 99.7 by 136.5 cm, Museum of Fine Arts, Boston. On Helicon's wooded slopes, Apollo sits with the nine Muses about the spring Hippocrene — lyres and pipes, scrolls and song — while below the sacred mountain a river valley of the last manner's pale immensity opens toward the sea; the winged horse Pegasus, whose hoof-strike made the spring, stands at the wood's edge; swans ride the water. Painted in 1680, in Claude's eightieth year, it is the late testament's picture of art itself — the sources of poetry, visited two years before the end.

The subject as summation

The choice cannot have been innocent, and the literature declines to treat it so: an old painter, his century's acknowledged poet of landscape, paints the fountain of poetry — inspiration's own geography — as one of his final large canvases. Claude had painted the Muses before (a famous earlier Parnassus is in Edinburgh); the Boston picture rethinks the theme in the 1680 tonality, and the changes read as self-knowledge: the divine company is smaller in the scene, the mountain's woods deeper, the valley below given more of the canvas — as if, at the end, even Parnassus mattered chiefly as a view: the Muses sing, and the song, made visible, is the distance. The spring at their feet feeds the river that feeds the valley that reaches the sea — inspiration's watershed, traced from source to horizon in one tonal course — and the entry knows no better image anywhere of what this catalogue's essay claims for Claude: that his true subject was always the passage from source to light.

Boston's late Claude

The canvas crossed to America in the twentieth century, giving Boston — whose collections lean early and grand-tour — a major late Claude, and the MFA hangs it as the American representative of the final manner: many US visitors meet 1680s Claude here first, and the museum's teaching (Boston's academic landscape tradition, from Allston forward, was Claude-formed) closes its circle on the picture. In the œuvre's geography it partners the Ashmolean's Ascanius: the last decade's two poles — art's mountain and epic's fatal grove — painted by the same ancient hand in the same pale air.

What to look at

Hippocrene at the Muses' feet — the small dark spring from which the whole luminous valley literally flows: the picture's argument in plumbing; Pegasus at the treeline, myth's engine grazing like one of Claude's own herds; the swans below (Apollo's birds, the valley's white notes); the Muses' circle, elongated late figures whose awkward grace suits beings never meant to persuade anatomically; and the distance — the true performance: an eighty-year-old's tonal staircase, step after step to a sea-bright horizon, unfaltering. Then the date again: 1680, gout in the hand, two years left — and the subject, of everything available to paint: where poetry comes from. The old man climbed Helicon on canvas and left the view as his account of the profession. The Liber records it near the book's last pages; Boston keeps it lit; the spring still runs downhill into the light.

Minerva visiting the Muses on Mount Parnassus (Cummer Museum, Jacksonville): wisdom calls on poetry at the sacred spring — the Helicon theme's companion thought, in the 1680 tonality of Boston's great canvas; Florida's Claude, the late Muses' southern American address.

Landscape with Noli me tangere (Städel Museum, Frankfurt): Easter morning as landscape — the risen Christ, taken for the gardener, and the Magdalene's arrested reach, staged small in a dawn valley: the painter of 'toward' ending his sacred œuvre on the gentlest 'not yet'. Painted 1681, among the last completed works; Frankfurt's Claude, hanging a floor from its Vermeer Geographer — two ways, one museum, of making light mean.

The picture

Oil on canvas, 120 by 150 cm, Ashmolean Museum, Oxford; signed and dated 1682. In a grove of colossal, translucent trees beside a bay, the boy Ascanius — Aeneas's son — draws his bow on the stag of Sylvia: the tame, garlanded deer of the Latin king's daughter, whose wounding (Juno's fury arranging it) will ignite the war between Trojans and Latins that fills the Aeneid's second half. The arrow is nocked, the stag turns, the temple-crowned headland and glassy water attend — and the instant holds, forever un-released. Painted in Claude's eighty-second year for Prince Colonna and finished months before his death on 23 November 1682, it is the last picture: the œuvre's deliberate, unsurpassable full stop.

The subject of the end

That the dying Claude chose this subject — of all Virgil — has moved every writer since Röthlisberger fixed the chronology: the smallest cause of the greatest ruin; peace's last second; a boy, a bow, a pet deer, and every war to come folded inside one arrow's pause. The embarkations painted departure as radiant threshold; the last canvas paints the threshold no one chooses — the moment before the irrevocable — and refuses, with a lifetime's discipline, to cross it: no wound is shown, no consequence; the light (palest silver-gold, the late tonality at its most rarefied) falls with perfect impartiality on hunter, victim and the world about to change. Critics reach for the same words — elegy, suspension, farewell — and the entry adds the structural one: reversal. Sixty years of Claude taught the eye to travel toward the light's promise; here the composition's deep glow lies beyond the stag, so that the promise and the target are one — the golden distance, aimed at. The old painter's last arrangement of his only subject is also its quietest self-judgment: beauty held at the instant before loss, which is, the picture seems to say, where it always lived.

The trees, and the manner's last state

Painters go to Oxford for the trees: the grove's enormous trunks and high translucent crowns — drawn with the trembling, spiritualised line of the last drawings — are unlike trees anywhere else in art, architecture grown organic, the coulisse-device sublimed into nave and clerestory; through them the bay's light arrives as if through glass. The figures are the late race at its most elongated (Ascanius nearly Gothic in his slenderness); the palette is the endgame's — ultramarine distances, pale golds, the warm grounds almost extinguished; and the handling, technical study confirms, is autograph throughout: no assistant, no decline — an ancient hand, perfectly informed, thinning matter toward light one last time.

History and afterlife

From Colonna's palace through the English collections, the picture reached the Ashmolean in 1926 — Oxford's reward, where it presides over the museum's landscape rooms as one of England's supreme Claudes outside London. Its afterlife is the late style's rehabilitation in miniature: long treated as the curiosity of a failing master, it was re-read by the twentieth century (Röthlisberger, Kitson, the 1982 tercentenary shows) as the œuvre's summit-stone, and it now closes every serious Claude retrospective and monograph — as it closes this catalogue's painted chronology — with an authority no other 'last picture' in landscape possesses. Poets and novelists have adopted it; museum labels call it a farewell; the entry prefers the plainer, stranger truth: it is a beginning, painted by a man out of time — the war's first second, the Aeneid's hinge, chosen by the painter of thresholds as the threshold on which to stop.

What to look at

The arrow — nocked, drawn, eternally unloosed: the œuvre's last held breath; the stag's turned head, garland just visible (tameness, the whole tragedy's fuse); the grove's crowns against the sky, the last and greatest trees; the temple on the headland — the gods, present and unhelpful; the bay's glass light beyond the fatal grove — the target and the promise, identical; and the signature with its date, 1682, the painter's final entry in the world's Liber. Then step back and take the leave the picture itself refuses: somewhere behind the varnish the arrow is still in the air, the deer still turning, the light still arriving from the sea — Claude Gellée of Chamagne, dying in Rome, left the world's most patient art at its most patient possible instant, and three and a half centuries have not moved it.
