Simon de Passe (1595-1647) was born in Cologne, the son of the engraver Crispijn de Passe (1567-1637) and his wife Magdalene (1555-1635). Of the couple's five childen four went on to become engravers, with Simon moving in 1616 to London where he became an accomplished portraitist known for engraving royal portraits such as the present examples. He left England in 1622, spending two years in Utrecht before moving to Copenhagen where he remained until his death in 1647.
E. Delieb notes that de Passe ...invented a method whereby a steel die was cut and wafer-thin disks of silver were struck with motifs, thereby imitating engraving by hand. (E. Delieb, Silver Boxes, London, 1986, p.17.). For a Charles II box, with very similar counters to the present examples see E. Delieb, ibid, p. 46.
