Pausanias was a Greek author, historian, and geographer of the 2nd century CE who journeyed extensively throughout Greece, chronicling these travels in his Periegesis Hellados or Description of Greece. 

His ten volumes of observations are treasured by both historians and archaeologists for their in-depth depiction of ancient Greece. He was far more than just a geographer; his travelogues included not only a description of an area's monuments, architecture and works of art but also its history, including the daily life of its people, ceremonial rites, customs, legends and folklore. Pausanias' work influenced the development of classical archaeology more so than any other text.
Although little is known of Pausanias' early life, and his birth year is hard to pin down (speculations range between 110 CE, 115 CE, and 125 CE), it appears he was born in Magnesia ad Sipylum, a city in the province of Lydia located in western Asia Minor. Because of his ability to travel so extensively, many assume he was well-educated and from a privileged class. There is some disagreement over when he began his Description of Greece. Some believe it may have been begun as early as 143 CE (which would have made him less than 20 years old) while others point to the more believable 155 CE. However, Pausanias seems to have ended his writing before 180 CE since no event after 176 CE is mentioned, and his death is generally placed in 180 CE.
While there may be some disagreement over when he began his travels, there is no doubt that his youth was spent during the reign of the Roman emperor Hadrian (117 CE – 138 CE) who was an admirer of all things Greek - especially the ancient Greek monuments of the Archaic and Classical periods.
The emperor's nurturing of a revival of Greek culture would have a profound effect on the young Pausanias (and with him many others); instead of focusing on events from his own time, Pausanias was drawn to the monuments and stories from the heyday of the independent Greek city-states.
