Sarmatia was a region of the Eurasian steppe inhabited by the Sarmatians. Maciej Miechowita (1457–1523) used "Sarmatia" for the Black Sea region and further divided it into Sarmatia Europea, which included East Central Europe, and Sarmatia Asiatica. Filippo Ferrari (1551–1626) also divided the two.
