1. Ptolemy established his own latitude and longitude places in the Roman
Empire. Since he was wrong by about 30 % he estimated the earth to be one
third smaller than it actually is. Even though a fellow by the name of
Eratosthenes had much better arithmetic than Ptolemy, 13 centuries later,
Columbus sailed out and took into consideration that the world was much
smaller than it actually is, thus taking into considration of Ptolemy rather than
Eratosthenes.
1000 years after the Roman Emopire, development of geographic findings
was quite slow. Still, they still had undiscovered lands and oceans and that
sustained the attention of some scholars.
The ancient Greeks had said that the Earth’s equalatorial zone was so hot that
human life was impossible there and the sun had scorched black the skins of
people living near. But the Arabs sailed acroos the equater and proved that
equatorial regions were habitable. Arab geographers made interpretations of
the evolution of mountain ranges and the depositon of sediments and analized
the atmospheric processes that produce particular weather patterns.
