Nice example of the scarce third state Ruscelli's map of Poland, Lithuania and the Baltic Region.
The map is bounded by the Vistula River and Prussia in the west, Livonia in the east, and Lithuania in the southeast. Centered on Riga and Vilna.
Ruscelli's Atlas is an expanded edition of Gastaldi's Atlas of 1548, which has been called the most comprehensive atlas produced between Martin Waldseemüller's Geographiae of 1513, and the Abraham Ortelius Theatrum of 1570.
Ruscelli and Gastaldi's maps were beautifully engraved on copper, marking a turning point in the history of cartography. From that point forward, the majority of cartographic works used this medium. As it was a harder material than wood it gave the engraver the ability to render more detail. Gastaldi sought the most up-to-date geographical information available, making the modern maps in Ruscelli's Geographia among the best modern maps of the period.
The third state can be identified by the addition of a sailings ship.
