Duccio was the most influential Sienese artist of his time and one of the key figures in the development of European painting. Duccio is considered to have had a major influence on the formation of the International Gothic style, and to have influenced Simone Martini and the brothers Ambrogio and Pietro Lorenzetti, among others.

His works include the Rucellai Madonna (1285) for Santa Maria Novella (now in the Uffizi) and the fabled Maestà (1308-11), his masterpiece, for Siena’s cathedral. Originally carried through the streets of Siena in a religious ceremony, the multi-paneled Maesta represented a major step forward in painterly style and narrative storytelling through visual art.

His Madonna and Child, painted on a wood panel around the year 1300, was purchased in November 2004 by the Metropolitan Museum of Art in New York City for an estimated sum in excess of 45 million USD, the most expensive purchase ever by the museum. In 2006 James Beck, a scholar at Columbia University stated that he believes the painting is a nineteenth century forgery; the Metropolitan Museum’s curator of European Paintings has disputed Beck’s assertion.
