Among the publishers, Michele Tramezini (fl. ca. 1546-1562), based in Rome, is perhaps the most interesting.  A large proportion of the material that he published was from original sources, or was re-issues of material published outside Italy.  Perhaps the most important part of his work, in the long-term, was the copying of the wall-maps of Jan van Deventer, depicting the provinces of the Low Countries.  Unfortunately, because of the vulnerability of wall-maps, it is often only through Tramezini's copies, albeit on a much reduced scale, that evidence of van Deventer's original work is preserved.  Indeed, when Gerard de Jode, the Antwerp publisher active from the 1550's to the 1590's, wanted to publish maps of the constituent provinces of the Low Countries, he turned to Tramezini's versions for a source, in the absence of van Deventer's originals (6).
Tramezini also published a reduction of Cornelis Anthoniszoon's 'Caert van Oostland ...', first issued in Antwerp in 1543, then re-issued in 1551, and circa 1560.  Of the first and second states, no example is known, while only one example of the third state survives.  He also published Fernando Alvares Seco's map of Portugal, circa 1561, which was the first separate printed map of the country.
