Denise Duval (Paris, 23 October 1921Bex, 25 January 2016) was a French soprano, best known for her performances in the works of Francis Poulenc on stage and in recital.
 During an international career, Duval created the roles of Thérèse in "Les mamelles de Tirésias", Elle in "La voix humaine", and excelled in the role of Blanche de la Force in "Dialogues of the Carmelites", leaving recordings of these and several other of her main roles.
Les Mamelles is an administrative district of the Seychelles, located in the south of the Greater Victoria (suburban) area on Mahé, the main island of the archipelago.
 The district is located inward from the adjacent coastal district of Roche Caiman.
 It is not to be confused with Mamelles Island some six kilometers northeast of Mahé.
Both of these were probably derived from the French play "Eustache de St Pierre, ou Le siège de Calais" by Hubert (pen name of Philippe-Jacques Laroche), which had been given in Paris in 1822 and was in turn taken from the 1765 play "Le siège de Calais" by Pierre-Laurent Buirette de Belloy.
 The historical basis was Edward III's siege of Calais in 1346, toward the beginning of what would later be called the Hundred Years' War.
The Siege of La Rochelle (French: "Le Siège de La Rochelle", or sometimes "Le Grand Siège de La Rochelle") was a result of a war between the French royal forces of Louis XIII of France and the Huguenots of La Rochelle in 1627–28.
 The siege marked the apex of the tensions between the Catholics and the Protestants in France, and ended with a complete victory for King Louis XIII and the Catholics.
Les Mamelles Lighthouse (French: "Phare des Mamelles" ) is a strategically important lighthouse situated near Cap Vert, the westernmost point of Africa, on the outskirts of Dakar the capital of Senegal.
 Completed in 1864, it has been described as "one of the world's great lighthouses, guiding ships around the western tip of Africa".
Le siège de Corinthe (The Siege of Corinth) is an opera in three acts by Gioachino Rossini set to a French libretto by Luigi Balocchi and Alexandre Soumet, which was based on the reworking of some of the music from the composer's 1820 opera for Naples, "Maometto II", the libretto of which was written by Cesare della Valle.
Democritus meditating on the seat of the soul ("Démocrite méditant sur le siège de l'âme") is a statue by Léon-Alexandre Delhomme (1841–1895), exhibited at the Paris Salon of 1868.
 It shows the Greek philosopher Democritus, his eyes fixed on a skull he holds in his hands.
 It is now exhibited in the garden of the musée des Beaux-Arts de Lyon.
The Breasts of Tiresias (French: "Les mamelles de Tirésias" ) is a surrealist play by Guillaume Apollinaire.
 Written in 1903, the play received its first production in a revised version in 1917.
 In his preface to the play, the poet invented the word "surrealism" to describe his new style of drama.
Les mamelles de Tirésias ("The Breasts of Tiresias") is an "opéra bouffe" by Francis Poulenc, in a prologue and two acts based on the play of the same title by Guillaume Apollinaire.
 The opera was written in 1945 and first performed in 1947.
The Road to Corinthe ( French: "La route de Corinthe" , Italian: "Criminal story" , also released as Who's Got the Black Box?)
 is a 1967 French-Italian Eurospy film directed by Claude Chabrol.
