Another of the good deeds of this worthy mayor was the foundation, through his executor, of a library to be attached to the Guildhall College, under the custody of one of its chaplains. This was duly carried out in 1425 by the erection of a separate building of two floors, well supplied with books "for the profit of the students there, and those discoursing to the common people." This public library, which appears to have been the first of its kind in England, had, unfortunately, but a brief existence, _all_ of its books having been "borrowed" in 1550 by the Duke of Somerset, Lord Protector, by whom, as we learn from Stow the historian, they were never returned. The loss has since been, to some extent, supplied by the present library, founded at Guildhall in 1824, and rebuilt in 1873. In the reign of Henry VI., after the completion of the great hall, other apartments, such as "the mayor's chamber, the council chamber, with other rooms above the stairs," were built. Of these no trace at present remains, and two Common Council chambers have since been erected. The first of these was a picturesque apartment, its walls being covered with statuary and paintings, the latter being chiefly presented to the Corporation by Alderman John Boydell. A new council chamber, of handsome and commodious design, was erected by the Corporation in 1884, from the designs of Sir Horace Jones, City Architect. The Court of Aldermen's present chamber was built in the latter half of the seventeenth century, and is a small but handsome room. The ceiling is painted with allegorical figures of the City of London--Prudence, Justice, Temperance, and Fortitude--executed by Sir James Thornhill, who was presented by the Corporation with a gold cup of L225 7s. in value. Around the walls and in the windows are shields containing the arms of most of the Lord Mayors of the last 127 years. [Illustration: THE GUILDHALL. _Engraved by R. Acom, 1828._]
