Giacomo Giovanni Rossi (1627-1691) was an Italian engraver and printer. He worked in Rome, heir to an important printing house founded by his father, Giuseppe de Rossi (1570-1639). Giuseppe started the press in 1633 and upon his death Giovanni and his brother Giandomenico (1619-1653) took over. The brothers expanded the business and by the mid-17th century it was the best-known printing house in Rome.
For his maps Giovanni collaborated with Giacomo Cantelli da Vignola. They produced the Mercury Geographical Atlas. The first edition is undated, but the second came out in 1692, a year after Giovanni's death. The maps were by Cantelli. The company also published maps based on those of Nicolas Sanson.
Subsequently the business passed to Lorenzo Filippo (1682-?). In 1738 the company was known as Chalcografia Camerale, then, from 1870 to 1945, as Regia Calcografica. Today the company is still in business and is called Calcografia Nazionale. It operates as a free museum and offers one of the best collections of prints and plates in the world
