“History doesn't repeat itself, but it does rhyme.”
Origins unclear. Earliest known match in print comes from 1970, in a collection called “Neo Poems” by Canadian artist John Robert Colombo, who recalled reading it sometime in the 1960s. Twain did say "History never repeats itself, but the Kaleidoscopic combinations of the pictured present often seem to be constructed out of the broken fragments of antique legends." in the 1874 edition of “The Gilded Age: A Tale of To-Day”. A thematic precursor, "History May Not Repeat, But It Looks Alike", appears in a 1941 article by Chicago Tribune in Illinois.
