Answer:
From what I can see, the route (image) is not being shown. But if I were you, I would choose the spots on the route that lead to Italy. Whether it is the fastest route or just simply leads to Italy. No one can really help any further without an image of the route (assuming there is one, and there probably is due to the format of the question), so maybe just post the question again with the image attached if my answer didn't help much.
People used to believe the earth is flat! (some people still do)
Eratosthenes
Using the knowledge that the Sun is very far away, the ancient Greek geographer Eratosthenes performed an experiment using the differences in the observed angle of the Sun from two different locations to calculate the circumference of the Earth.
He conceived the idea of separating government authority into the three major branches: executive, legislative and judicial. This perspective significantly influenced the authors of the Constitution in establishing laws and division of duties, and also in the inclusion of provisions to preserve individual liberties.
