Nice example of this late state of Sanson's first map of Portugal. The map includes a highly decorative 17th-century style cartouche. The map was first issued in 1654, with this example reissued in 1704.
The map is highly detailed, showing the many rivers, hills, cities, and other geographical features in this part of the world. Inland, Castille and Leon are named, and Seville can be seen in the far southeast. Of course, this map is focused on Portugal so Lisbon and the Tagus River are well displayed.
The son of famous French cartographer Nicolas Sanson, Guillaume (1633-1703) carried on his father's work. Like his sire, he was a court geographer to Louis XIV. He often worked in partnership with another prominent cartographer of the time, Hubert Jaillot.
