Question: Are  Jean Cocteau and Bernard Cornwell both writers and authors?
Context: The Jean Cocteau House was the residence of the French poet, artist, playwright and film maker Jean Cocteau (1889–1963), which he purchased with the film actor Jean Marais in 1947, and where he created many of his later works before his death in 1963.  It is located about fifty kilometers south of Paris in the village of Milly-la-Forêt in the Essonne Department of France.  The 16th century house was originally part of the domain of a 13th-century chateau whose moat and a ruined tower are next to the house.  The house also has gardens and a small wooded park.  The house now displays furnished rooms and a museum of his work.  The tomb of Cocteau, decorated with his work, is found in a small chapel, Saint Blaise des Simples, at the edge of town not from the house.  The house facade and roof were listed in the supplemental inventory of historic monuments in 1969.
