Philippe Buache map of Antarctica, made in Paris in 1737, a
century before Antarctica was discovered. Evidently copied frm
maps surviving from ancient times, it shows Antarctica as two
separate land masses, a fact no established until the Geophysical
Year of 1958 through ice soundings, but evidently known to navigators
of prehistory, who may have visited Antarctica before it was
covered by ice.
