p 449 | The Théâtre de l'Odéon is one of France's six national theatres. It is located at 2 rue Corneille in the 6th arrondissement of Paris on the left bank of the Seine, next to the Luxembourg Garden. It was originally built between 1779 and 1782, in the garden of the former Hôtel de Condé, to a Neoclassical design by Charles De Wailly and Marie-Joseph Peyre. The Odéon was originally intended to house the Comédie Française, which, however, preferred to stay at the Théâtre-Français in the Palais Royal. The new theatre was inaugurated by Marie-Antoinette on April 9, 1782.
p 450 | Even though Moncrieff uses "-ast" here, the French has "-arder", which Sturrock suggests could possibly stand for pétarder, meaning "to blow one's top" -- and possibly several other slangy meanings. I think Moncrieff used his translator's licence to indicate that the two men were gossiping about Charlus being gay (i.e., "pederast"). Remember Marcel has already indicated that the people in one's social circle wouldn't mention or notice it, but outsiders would do both.

p 455 | Le Capitaine Fracasse by Théophile Gautier: This book was promised to the public in 1836 but finally published in 1863. It is centered on a soldier named Fracasse whose adventures portray bouts of chivalry, courage and a sense of adventure. Gautier places the story in his favourite historical era, that of Louis XIII. It is best described as a typical cloak-and-dagger fairy tale where everyone lives happily ever after.
