The diamond-point engraving on this ceremonial covered goblet is executed in a manner very close to that of the great Dutch amateur glass engraver Willem van Heemskerk. The bowl of the goblet is engraved with the words Salus patriæ et Ecclesiæ (Welfare of country and church), and the lid bears the words Libertatis et Religionis (Of freedom and religion). The highly accomplished engraving has all the freedom of the finest contemporary seventeenth-century ink-and-paper calligraphy. The fluid scrolling flourishes of the script, encompassing the whole of the bowl of the glass, are expansive to the point of becoming pure ornament.
