ORIGIN OF THE SUBJECTS As we said, in most cases cameos depict subjects from the traditional iconography. Is interesting to see how the same subject is depicted over the centuries and sometime over the millenniums! Since cameos were always collected by any emperor, king, price, noble, Pope etc, in most cases these collections were catalogued in illustrated. This allowed carvers to know the ancient and antique pieces, and made "copies" of them. So, we can see the same Athena on a Greek cameo, on a Neoclassical cameo and on a modern one. Most of the subjects come from the cameo iconography, but in many cases from sculptures, paintings and frescos. Most subjects are mythological or religious. During the late Victorian Era, above all in England, were very popular cameos depicting country scenes. Among the artists inspiring carvers of the 19th Century we can mention Thorvalden (sculptor and cameos carver), Raphael, Guido Reni, Louis David and many others. Here are a few samples: Since the photography was not yet invented in 19th Century, famous cameos and cameos collections were illustrated on books, or moulded on plaster. We can still find such plasters sold by antiques dealers. These copies were normally sold in boxes in shape of book, or fixed in small drawers. Each cameo was accurately described. This is an important resource for to know the history of the antique and celebrated cameos, identify the subjects, or who was the carver etc.
