I · THE OBJECT · BRITISH MUSEUM

The Tughra of Suleiman the Magnificent

Ottoman · Early Modern · Calligraphic monogram

A limestone cave wall painted with large animals in dark pigment: horses, cattle and deer, some overlapping, their bodies following the natural curves of the rock.

III · THE WORK · ART HISTORY

The Painted Caves of Lascaux

Dordogne, southwestern France · Estimated 17,000 to 22,000 years ago · Mineral pigment on limestone

Hundreds of animals drawn on limestone walls far from daylight, using the rock's own bulges to give them volume. The site is now closed — opening it to visitors began to destroy it.
