Representation
of the Earth
Some editions of the book
begin with a globe on the title page, fittingly turned to the
Old World. The globe appears again later in the work, suggesting
its central importance. Three other instruments, perhaps to represent
time and latitude, are also present: a Nuremberg-style diptych
dial (on the
horizon ring), a pillar
dial (lower right)
and a quadrant (under
the globe). |
