Giuseppe Rosaccio was born in Pordenone around 1530. He graduated in philosophy and medicine at the University of Padua. He worked as a cosmographer, historian, cartographer, astronomer, astrologer, physician, traveller, art chronicler, encyclopedist, and even as a bookseller.
In 1606 he obtained the privilege of printing his works from the Grand Duke of Tuscany. However, between 1607 and 1608 he worked in Bologna, carrying out his activity as a street doctor and astrologer. Thanks to the protection of cardinal Benedetto Giustiniani, Rosaccio was able to defend himself from the attacks of the Bologna Academy, who considered him a charlatan.
