At the end of the nineteenth century French potters were strongly influenced by the naturalistic forms and variegated glazes of Asian ceramics. In 1900 at Sèvres, Léon Kann designed a number of gourd-shaped vases. The mellifluous lines and subtly graded coloring of this example merge an Asian aesthetic with the last flowering of the Art Nouveau style. A gentle spiral movement is sustained by the curve of the flowering vine and the artful placement of the snails. This object, mnade in 1900, is now in the collection of the Metropolitan Museum of Art .
The two snails are specimens of Cepaea nemoralis (L., 1758). The upper one of dextral, the lower one sinistral. Both are yellow banded morphs.
