Research by Piers Percival into this maker (see P. Percival, 'John Evans, Maker of Steeple Cups', The Silver Society Journal, 2000, no. 12, pp. 128-133) has revealed both his identity and some 14 cups by him dating from between 1594 and 1617. Several of these are markedly German in character and at least one may be a direct import made presumably in sterling standard so it could be hallmarked in England and thus legally sold there. There were, however, several hundred alien goldsmiths who were not allowed to open their own workshop but who were working in London at this period. It seems probable that one or more of these foreign workers supplied John Evans with cups that he submitted for marking. This may well explain the unusual form of this rare London marked nautilus-cup, a form which is most often the work of Augsburg or Nurmeburg silversmiths.
