Pepy's Diary. 26 Mar 1666. Our [meeting] being done, my Lord Bruncker (age 46) and I to the Tower [Map], to see the famous engraver (age 34), to get him to grave a seale for the office. And did see some of the finest pieces of work in embossed work, that ever I did see in my life, for fineness and smallness of the images thereon, and I will carry my wife thither to shew them her. Here I also did see bars of gold melting, which was a fine sight.

Evelyn's Diary. 20 Jul 1678. I went to the Tower [Map] to try a metal at the Assay-master's, which only proved sulphur; then saw Monsieur Rotière (age 47), that excellent graver belonging to the Mint, who emulates even the ancients, in both metal and stone; he was now molding a horse for the King's (age 48) statue, to be cast in silver, of a yard high. I dined with Mr. Slingsby (age 57), Master of the Mint.
