Periplus

What is a Periplus?

A periplus was a very old book that helped sailors. It listed important places like ports and landmarks along the coast. It also told how far apart these places were. This helped captains know what to expect when they sailed near shore.

Think of a periplus like a map for the sea, but written down instead of drawn. These books were very useful for ancient sailors. They were like a logbook that guided ships from one place to another.

Why Do We Know About Them?

The idea of a periplus goes back a very long way, even to the time of early Greek historians. Famous writers like Herodotus and Thucydides used information from these documents in their stories. So, peripli were an important way that people shared their knowledge of the world and helped others travel safely.

Different Kinds of Peripli

Many important travel guides called peripli have been found. These guides listed ports and landmarks along coastlines to help sailors. For example, there was the Periplus of Hanno the Navigator, a Carthaginian explorer who sailed along the coast of Africa. There was also the Periplus of the Erythraean Sea, which described the coast of the Red (Erythraean) Sea and talked about the coast of India and Africa.

These old books helped people learn about faraway lands and made travel by sea safer and easier.
