Of Cristiano Dehn, the British Museum notes that he was a, 'Manufacturer of casts of engraved gems. Worked as assistant to Baron von Stosch as producer of glass and sulphur impressions, first in Rome from at least 1728, then in Florence. In 1739 Dehn returned to Rome, establishing his own business in gem impressions in the via Condotti. His shop was later in the via Babuino, then in the Corso. His casts after gems were mentioned in the letters of Goethe and Winckelman and they sold so well that his son-in-law, Federico Dolce, who had married Dehn's daughter Faustina, continued the shop long after Dehn's death. Dehn's collection of casts numbered over 28,000 and was eventually bought by James Tassie (Queen Victoria). In 1772 Dolce published a catalogue of Dehn's impressions, with a portrait of Dehn as the frontispiece (Zazoff 1983, pl. 41, 3). His descendants continued the business well into the 19th c.'
