"Rare are those who have traveled to this southern land; thus neither the inhabitants nor products are known."
The colossal southern land mass stretching across the lower quarter of Ricci's map, which he calls Magellanica, includes Australia, Antarctica, New Guinea, and much hypothesized land. Notoriously dangerous, the southern seas were the last frontier in the Age of Exploration. Sailors complained of the mountainous waves and areas of shallow waters and sharp rocks that claimed countless lives. Australia was not circumnavigated by Europeans until 1642, and New Zealand not until 1770. Antarctica was first sighted in the early 19th century.
