George Smith and F.B. Benger. A collection of armorial bookbindings. London, Ellis, 1927 identified this as the stamp of `Kyle of Scotland', an identification repeated by E. Ph. Goldsmith in his standard work Gothic and Renaissance bookbindings. 2 vols. London, 1928, and accepted by Clements. George Mackenzie of Rosehaugh in his Science of heraldry published in Edinburgh in 1680, and written before 1672, says "The name of Kyle, with us, or, three candlesticks sable". The two great French authorities on armorial bookstamps, Guigard and Olivier, assign the stamp to Charles Largentier (1619 1704). The binding on the Aemylius is continental and there seems insufficient reason to seek a Scottish provenance for the stamp.
