The Aegean sea.... Your welcome :]
The most common way for ancient Greeks to travel was by foot or by sea. They often walked or used boats to get from place to place.
The Ancient Greeks traveled by the sea because the land was to mountainous to travel by foot. The Ancient Greeks traveled by foot, cart, chariot and ship.
Because that was there main route of Transportation. And it help them discover more lands.
They would travel across the Aegean and Mediterranean Sea.
Take a look at ancient Greece on a map. There are many islands and much coastland. Travel by water is much faster than by land. The ancient Greeks traded with many people all around the Mediterranean.
Aegean Sea
the Greeks lived on the Mediterranean Sea... so I would say that one. They knew of the Black sea and the Caspian sea; and the ancient Greeks believed the Atlantic Ocean to be a world encompassing sea.
The ancient greeks ate many wierd foods such as pigs, sea urchins, pigeons, olives and grains.
I would say the Mediterranean Sea, because you could easily travel anywhere in the known world on it back then, and both Rome and Greece were world powers. It also served as a huge trade route.
Remember that ancient Greece was ancient and imports came from very close by. Travel was slow and harsh.
They used the sea.
Well, maybe this could give you a clue. Ancient greeks made their trading through and across the Mediterranean Sea.
