From ancient times, sailors used some methods and tools to know their position at sea with some approximation. A part of these instruments have been maritime path routes, and were based on the travel diaries and the experiences lived by sailors on their voyages.
At that time, these routes were the only navigational charts, such as the one by Piteas of Marseille, due to his knowledge of the climates of the Earth, and Hannon, which provided all the details of his journeys.
As we can see, the drafting of the paths preceded the preparation of nautical charts, for sailors of that era information written on the sea in which they sailed was most reliable.
