Robert SIDNEY, 4th Earl of Leicester 1649-1702

Biographical Note

Son of Philip Sidney, 3rd Earl of Leciester, of Penshurst, from whom he inherited the title and estates in 1698.


The Sidney family library at Penshurst began to be developed in the 16th century but was substantially built up by the 1st and 2nd Earls. We do not know the size of the library by the time of the 1st Earl’s death, but a series of commonplace books demonstrate a wide range of reading, and a few books of his, some in handsome bindings, survive in various libraries. A catalogue of the Penshurst library compiled by Gilbert Spencer in the 1650s/60s lists ca.4800 volumes, showing the extent of its growth under the 2nd Earl. The published account of the library by Warkentin and others, which includes speculation as to how it might have been housed, comments on the breadth and eclecticism of the library, with up to date publications in various European languages, on many subjects.

After the 2nd Earl’s death it was less augmented by later family members, although there is at least one book at Penshurst today, a French Bible, with a purchase inscription of the 4th Earl, dated 1669. The whole collection was sold by the 7th Earl in 1743 to the London bookseller Thomas Osborne, who promptly dispersed it via a series of sales for which no catalogues survive. Only a small number can be traced today, in various libraries around the world. Examples: Bodleian J-J Sidney 183, Gough, Chetham’s Library DD4 28 18124.

Characteristic Markings

Many of the books acquired at Penshurst during the 17th century were not inscribed or otherwise marked, which is why so few can be traced today. A number of books with armorial stamps associated with the 1st Earl are recorded in the Armorials Database (some of these relate to the books bought for Oxford); the 5th Earl had a bookplate made dated 1704 (Franks 28696-7, *41, *56).
