The fact that the Pope used the terms "from pole to pole"
in describing the dividing line has been used by some South American geopoliticians,
especially from Argentina and Brazil, to argue that the Pope was also dividing
up the (as of then) undiscovered continent of Antarctica between the Portuguese
and Spanish crowns. The issue has contemporary significance in terms of
the competing claims of Argentina, Chile and Great Britain in the portion
of Antarctica which faces South America.
