The opera is based on the Biblical tale of Samson and Delilah as recounted in the Old Testament's Book of Judges, chapters 16. It is the only opera by Saint-Saëns that is regularly performed. The second act, the love scene in Delilah's tent, is one of the set pieces that define French opera. Two of Delilah's arias are particularly well known: "Printemps qui commence" and "Mon cœur s'ouvre a ta voix" ("My heart opens itself to your voice", also known as "Softly awakes my heart"), the latter of which is one of the most popular recital pieces in the mezzo-soprano repertoire.
