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. Simon moved to London in 1616 where he became an accomplished portraitist known for engraving royal portraits such as the present examples.
Eric 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." (Eric Delieb, Silver Boxes, London, 1986, p. 17). For a Charles II box, with very similar counters to the present examples see: Delieb, ibid, p. 46.
