[3] Coppo's major work was the description, accompanied by an atlas of 22 maps, of the entire known world, titled De toto orbe.
[4] The two preserved samples of the work are kept in Bologna (Biblioteca comunale dell'Archiginnasio) and in Paris (Bibliothèque nationale de France).
This work contained 15 systematically arranged woodcut maps, named Tabulae ("tables"), to be published in a book, thus representing the first "modern" atlas, though this distinction is conventionally awarded to Abraham Ortelius.
[8][2] Two manuscripts of De Summa totius Orbis and Portolano, bound in a single text-block, together with printed woodcut maps, are kept in the Sergej Mašera Maritime Museum in Piran.
It is unique primarily because, unlike other preserved works by Coppa, it contains 15 colorized, systematically-arranged, woodcut maps.
