Binding for William IV, Prince of Orange (1711-1751) (L.6.1)
Gold-tooled vellum binding to Johann Kaspar Suicer's Thesaurus ecclesiasticus (Utrecht, 1746), incorporating two sets of arms: one on the front cover with two mottoes, "Honi soit qui mal y pense" (the motto of the British Royal family) and "Je maintiendrai" (the motto of the House of Orange); and another without a motto. The provenance has been attributed to Willem Karl Hendrik, later William IV, Prince of Orange, and husband of Anne, daughter of George II.
