Jean de Chelles

Jean (or Jehan) de Chelles[1] (French pronunciation: [ʒɑ̃ də ʃɛl]; working 1258–1265) was a master mason and sculptor who was one of the architects at the Cathedral of Notre-Dame de Paris.

On the exterior wall of the south transept a stone plaque is signed Johanne Magistro and dated February 1257, documenting the initiation of alterations to the transept and its portal.

Jean de Chelles is credited with the south end of the transept of Nôtre Dame de Paris, the portal of the cloister and its rose window, and the portail Saint Etienne.

He is supposed to have worked with Pierre de Montreuil on the Cathedral of Saint Julien, Le Mans.

[2] He is sometimes thought to have worked on the Sainte-Chapelle in Paris, but the art historian, Robert Branner, believes this to have actually been created by Thomas Cormont, who had previously worked at Amiens.
