…yet I scarcely hope to be believed that I state, however solemnly, that my poor father put me, when I was about fifteen years of age, into the counting-house of what he termed "a respectable hardware and commission merchant doing a capital bit of business!" A capital bit of fiddlestick!
-- Edgar Allan Poe, "The Business Man," Burton's Gentleman's Magazine, February, 1840
"A fiddlestick about men of genius!" Warrington cried out, who was a very severe moralist upon some points, though possibly a very bad practitioner.
-- William Makepeace Thackeray, The History of Pendennis, 1850
Fiddlestick stems from the late Middle English word fidillstyk, referring to the bow with which one plays a fiddle.
