Salammbô was a projected opera conceived by Russian composer Sergei Rachmaninoff around 1906.

[1] Previously, he had made no written mention of this, but it is clear that he put great thought into the project, evidenced by a letter that he wrote to his friend Nikita Morozoff on March 19, 1906, which gives a scene-by-scene outline.

The letter also requests that his friend contact Mikhail Svobodin, a journalist known for poetry, and ask him to write the libretto.

[2] Svobodin did not respond, so Morozoff attempted to write some, but Rachmaninoff rejected his work in favor of another friend, Mikhail Slonoff.

A few days after the letter, Rachmaninoff's wife and daughter became sick and the project was terminated.
