What Men Live By, H. 336

What Men Live By (Czech: Čím lidé žijí) is an opera in one act by Bohuslav Martinů to an English libretto by the composer, based on Where Love Is, There God Is Also (1885) by Leo Tolstoy, though he chose to use the more universal title of a different Tolstoy story What Men Live By (1886). It was composed in 1951-1952 when the composer was living in the United States, and described by him as a 'pastoral-opera'.
