The title was suggested by Steinbeck's first wife after hearing the song, The Battle Hymn of the Republic. "Mine eyes have seen the glory of the coming of the Lord/He is trampling out the vintage where the grapes of wrath are stored." The song by Julia Ward Howe is an allusion to Isaiah 63: 4-6. The novel has allusions to vineyards and grapes throughout to continue the allusion. Steinbeck liked the title because it was a march, and he felt this novel was revolutionary. The title gave it a patriotic flavor as well. Steinbeck was hoping to calm critics who would say it had a Communist leaning.
