In Great Britain in the early 1770s, the word "macaroni" did not only mean the pasta, but also a young man who had returned from the grand tour bringing with him foreign fashions and exotic tastes, including the still little known noodle dish. The unknown English caricaturist emphasises in particular a central characteristic of this dandy: the opulent haircut bolstered out with horsehair.
