Answers
Finding one’s way on land or by sea has been the essential element to survival since the beginning of time. Knowing which paths led from one town to the next benefitted tradesman in their pursuit of selling their goods. Along the way markers and signs allowed people to move about quickly without fear of getting lost. Sailors did not necessarily have marked paths to prevent their loss of direction and possible fate of dying at sea. Navigation relied on staying close to the shoreline. They used landmarks to note their location. They shared this information with other sailors that allowed the establishment of trade routes.
The original ancient sailors knew that the best way to navigate the sea revolved around the celestial stars. If they were able to locate north and south accurately their chances of survival increased. Many devices were created throughout the centuries to aid them when crossing great seas and oceans. Leaving the shoreline to venture further out to sea using these devices opened up worldwide trade routes and discoveries of new lands.
