In 1990 Italy issued a stamp commemorating
the centenary of the SocietÓ Dante Alighieri. The design has a
portrait of Dante, an open book, possibly representing the Divina
Commedia, and a globe. Dante lived from 1265 to 1321; the earliest
globe was made by Martin Behaim in 1492, nearly two hundred years
later. I do not know what connection the globe has with Dante, so at
this point it appears to be an error.
Also, the globe shows Europe and Asia, the Antarctic
and Australia. Apart from Europe the maps of the continents reflect
discoveries much later than Dante, and further, the northwestern part
of Asia is misshapen, and the Antarctic continent is too far North.
