Holborn Court must have included South Square and Field Court, the latter so called from its being a passage into the Red Lion Fields,[60] where a Bowling-Green was laid out in the seventeenth century. When, at the close of that century, Dr. Barebone, the great builder, bought Red Lion Fields and began to build upon that site, ‘the Gentlemen of Graies Inn took notice of it, and thinking it an injury to them, went with a considerable body of 100 persons, upon which the workmen assaulted the gentlemen, and flung bricks at them, and the gentlemen at them again, so a sharp engagement ensued, but the gentlemen routed them at last.’[61] The principal entrance to Gray’s Inn was formerly from Gray’s Inn Lane. It was not till the end of the sixteenth century that, as Stow puts it, ‘the Gentlemen of this House purchased a messuage and a curtillage situate upon the south side of this House, and thereupon erected a fayre gate and a gatehouse, for a more convenient and more honourable passage into the High Street of Holborne, whereof this house stood in much neede, for the former gates were rather posterns than gates.’ By Gray’s Inn Gate, Jacob Tonson, Pope’s publisher, kept his shop before moving to Fleet Street. Soon after Holborn Gate was erected, the shop underneath was taken by another bookseller, one Henry Tomes by name, who, appropriately enough, published the first edition of Bacon’s ‘Advancement of Learning.’ The Entrance Gate from Holborn leads us from the throng and bustle of the streets, the din and rush of the City, and the noisome fumes of twopenny tubes and motor-buses, through a dull and narrow alley into South Square--a large, irregular quadrangle of pleasing, harmonious eighteenth-century houses. Opposite the entrance passage a detached block faces us (No. 10), containing the Common Room, admirably rebuilt in 1905. This is connected by an archway with the Hall, Chapel, and Library. The foundation of the Library has been [Illustration: A DOORWAY IN SOUTH SQUARE, GRAY’S INN IT is one of several classic entrances of this type in the Square, and bears the date 1738.] attributed to Francis Bacon, Lord Verulam. But references to it occur before 1576, the year in which he became a Member of the Inn.[62] But it was not till 1737 that the need was felt for the erection of a building specially intended to house it. Then an Order was passed for building a Library in Holborn Court, now known as South Square. A hundred years later additions were made, and in 1883 a new Library building was added, which is entered separately from the internal angle of South Square, and which fronts externally upon the then newly-made Gray’s Inn Road. The Library boasts a small but valuable collection of manuscripts, including that of Bracton’s ‘De Legibus et Consuetudinibus Angliæ.’
