Rock

Rock is a subject in art. The gallery holds 69 works in this subject in art, including works by Titian, Thomas Cole and Albert Bierstadt.

In geology a rock, or stone, is any naturally occurring solid aggregate of minerals or mineraloid matter, classified by composition and by the way it forms—igneous, sedimentary, or metamorphic. Yet long before science codified them, rocks were among the oldest and most charged subjects in art, prized as the enduring substance of the earth itself. Classical Chinese landscape theory made the idea explicit: in the eleventh-century treatise associated with the Northern Song master Guo Xi (c. 1020–c. 1090), rocks are called the "bones" of the mountain, water its blood and foliage its hair. Within the shanshui ("mountain-water") tradition, and in the parallel cult of gongshi or scholars' rocks—collected as passionately as paintings by Song literati such as Mi Fu and Su Shi, and judged by qualities of thinness, openness, perforation and wrinkling—stone became a vehicle for contemplating the energies of nature.

In Europe the rock acquired its full symbolic weight with Romanticism. For Caspar David Friedrich the boulder signified permanence and immovable faith: in Two Men Contemplating the Moon (first version 1819–20), two figures seen from behind stand among gnarled rocks and an uprooted oak, drawing the viewer into a sublime communion with the landscape. The motif fused geological fact with spiritual meaning.

The nineteenth century pressed that fusion toward scientific exactitude. John Ruskin, in Modern Painters, argued that "the laws of the organization of the earth" were the foundation of all landscape truth, and his call for fidelity to nature shaped a generation. America's Hudson River School—Thomas Cole, Frederic Edwin Church, and the Ruskin-inspired William Trost Richards among them—made geological accuracy a point of honour, producing meticulous rock studies; an interest in geology even functioned as a marker of social standing. This catalogue's holdings sit squarely in that lineage: Albert Bierstadt's Lake Lucerne, Jasper Francis Cropsey's Autumn—On the Hudson River, William Trost Richards's Indian Summer, Martin Johnson Heade's Rio de Janeiro Bay, and Alfred Thompson Bricher's Marine Landscape, whose sea-worn ledges typify the luminist coastal study.

That legacy carried forward—into Cézanne's structural studies of the rocks at Fontainebleau and Bibémus, and ultimately the earth-as-medium of twentieth-century Land Art—keeping stone a touchstone for art's dialogue between nature, time, and form.
