Pausanius (l. 110-180 CE) was a geographer and historian who traveled extensively, taking notes on points of interest, then wrote on them in guide books which could be used by tourists visiting the sites described. His works have long been recognized for their accuracy and have served as guides for archaeologists and historians in the modern era as in antiquity.
