Goose and Gridiron
A public-house sign, properly the coat of arms of the Company of Musicians—viz. a swan with expanded wings, within a double tressure [the gridiron], counter, flory, argent. Perverted into a goose striking the bars of a gridiron with its foot, and called “The Swan and Harp,” or “Goose and Gridiron.” This famous lodge of the Freemasons, of which Wren was Master (in London House Yard), was doomed in 1894.
