upstart crow

Nor must we forget, that, in his own life-time, Shakespeare was not Shakespeare, but only Master William Shakespeare of the shrewd, thriving business firm of Condell, Shakespeare & Co., proprietors of the Globe Theater in London; and by a courtly author, of the name of Chettle, was hooted at, as an "upstart crow" beautfied "with other birds' feathers."

—Herman Melville, "Hawthorne and His Mosses," The Literary World, August 17 and 24, 1850
