There are few notices of the London fairs in contemporary memoirs and journals, and as few advertisements of showmen have been preserved by collectors of such literary curiosities, between the last visit to Southwark Fair recorded by Pepys and the period of the Revolution. The public mind was agitated during this time by plots and rumours of plots, by State trials and Tower Hill executions, which alternately excited men to rage and chilled them with horror. Giants and dwarfs, and monstrosities of all kinds, seem to have been more run after, under the influence of these events, than puppets and players. Take the following as an example, an announcement which was printed in 1677:-- "At Mr. Croomes, at the signe of the Shoe and Slap neer the Hospital-gate, in West Smithfield, is to be seen _The Wonder of Nature_, viz., A girl about sixteen years of age, born in Cheshire, and not much above eighteen inches long, having shed the teeth seven several times, and not a perfect bone in any part of her, onely the head, yet she hath all her senses to admiration, and discourses, reads very well, sings, whistles, and all very pleasant to hear. God save the King!" The office of Master of the Revels, which had been held by Thomas Killigrew, the Court jester, was conferred, at his death, upon his son, who leased the licensing of ballad-singers to a bookseller named Clarke, as appears from the following announcement, which was inserted in the _London Gazette_ in 1682:-- "Whereas Mr. John Clarke, of London, bookseller, did rent of Charles Killigrew, Esq., the licensing of all ballad-singers for five years; which time is expired at Lady Day next. These are, therefore, to give notice to all ballad-singers, that take out licenses at the office of the revels, at Whitehall, for singing and selling of ballads and small books, according to an ancient custom. And all persons concerned are hereby desired to take notice of, and to suppress, all mountebanks, rope-dancers, prize-players, ballad-singers, and such as make show of motions and strange sights, that have not a license in red and black letters, under the hand and seal of the said Charles Killigrew, Esq., Master of the Revels to his Majesty."
