The lands of the Mediterranean Sea produced a remarkable evolution in travel. People travel for trade, commerce, religious purposes, festivals, medical treatment, or education developed at an early date.
Guidebooks became available as early as the fourth century BC, covering a vast area of destinations, i.e. Athens, Sparta and Troy. Pausanias, a Greek travel writer, produced a noted “description of Greece” between AD 160 and 180, which, in its critical evaluation of facilities and destinations, acted as a model for later writers. Advertisements, in the form of signs directing visitors to wayside inns, are also known from this period. However, under Romans rule is where international travel became first important. With no foreign borders between England and Syria, and with the seas safe from piracy due to the Roman patrols, conditions favoring travel had arrived. Roman coinage was acceptable everywhere, and Latin was the common language. Romans travelled to Sicily, Greece, Rhodes, and Troy, Egypt and from the third century AD, to the Holy Land.
This era also saw the birth of travel writing. Herodotus was the worlds' first travel writer. Guidebooks also made their appearance in the fourth century covering destinations such as Athens, Sparta and Troy. Advertisements in the way of signs directing people to inns are also known in this period.
