J.J. Sylvester was a brilliant mathematician but, by all accounts, a lousy poet. The Dictionary of American Biography opines delicately that “Most of Sylvester’s original verse showed more ingenuity than poetic feeling.”

What it lacked, really, was variety. His privately printed book Spring’s Debut: A Town Idyll contains 113 lines, every one of which rhymes with in.

Even worse is “Rosalind,” a poem of 400 lines all of which rhyme with the title character’s name. In his History of Mathematics, Florian Cajori reports that Sylvester once recited “Rosalind” at Baltimore’s Peabody Institute. He began by reading all the explanatory footnotes, so as not to interrupt the poem, and realized too late that this had taken an hour and a half.

“Then he read the poem itself to the remnant of his audience.”
