The accuracy of the Piri Reis map is mixed. The Iberian peninsula and the coast of Africa, well known to cartographers of the time, are depicted accurately. Island groups in the eastern Atlantic are accurately placed but not drawn to proper scale. The northern portion of the South American coast is also rendered fairly accurately and positioned correctly across from Africa. Much of the Caribbean also is mapped fairly accurately, perhaps reflecting Christopher Columbus's recent maps of the region. However, the area representing North America bears little resemblance to the actual coastline except for one projection which might portray Newfoundland. An island nearby labeled "Antilia" might be Nova Scotia since a note there refers to the legendary voyages of Saint Brendan. Arguably, much of the area to the north of the Caribbean may be based on maps of the Asian coast, reflecting contemporary confusion about exactly what had been discovered to date.
