The "periegesis", or "progress around" was an established "literary" genre during the Hellenistic age. A lost work by Agaclytus describing Olympia () is referred to by the Suda and Photius. Dionysius Periegetes (literally, Dionysius the Traveller) was the author of a description of the habitable world in Greek hexameter verse written in a terse and elegant style, intended for the "klismos" traveller rather than the actual tourist on the ground; he is believed to have worked in Alexandria and to have flourished around the time of Hadrian. An early "remarkably well-informed and interesting guidebook" was the "Hellados Periegesis" ("Descriptions of Greece") of Pausanias of the 2nd century A.D. This most famous work is a guide to the interesting places, works of architecture, sculpture, and curious customs of Ancient Greece, and is still useful to Classicists today. With the advent of Christianity, the guide for the European religious pilgrim became a useful guidebook. An early account is that of the pilgrim Egeria, who visited the Holy Land in the 4th century CE and left a detailed itinerary.
