Ptolemy’s Geography is essentially an atlas of the world as it was known to Ptolemy and his contemporaries 1,900 years ago. Bill Thayer has provided an English edition of Ptolemy’s Geography, an edition that is, by his own admission, “is hardly a scholarly one.” What is interesting is that, in addition to providing an English version of the text, Bill has also created maps using the coordinates and the instructions provided by Ptolemy in his book. The site seems to be a work in progress as not all maps and chapters are complete.
