The art form that Cornell made his own was the box, its contents carefully arranged to evoke a mood or narrative. These works may recall toys the artist had played with as a child, but they must also trace back to devices in Surrealist art (which Cornell knew well) and, earlier, in paintings by Giorgio de Chirico. In Taglioni's Jewel Casket, small glass cubes lie in a wood box. Beneath them, and under blue glass, necklaces, sand, crystal, and rhinestones rest on a mirrored surface. This romantic scene of ice and jewels relates to an event in the life of the legendary nineteenth-century ballerina Marie Taglioni.
A label in the box's lid tells the story: "On a moonlight night in the winter of 1835 the carriage of Marie TAGLIONI was halted by a Russian highwayman, and that enchanting creature commanded to dance for this audience of one upon a panther's skin spread over the snow beneath the stars. From this actuality arose the legend that to keep alive the memory of this adventure so precious to her, TAGLIONI formed the habit of placing a piece of artificial ice in her jewel casket or dressing table where, melting among the sparkling stones, there was evoked a hint of the atmosphere of the starlit heavens over the ice-covered landscape."
