ABSTRACT
Despite the exiguity of the remains, it appears that one can determine the focus of Dikaiarchos' work on geography. In this brief survey of the sherds, It tries to summarize his interests and accomplishments in a synoptic way, placing them in their proper historical context. Dikaiarchos seems to me to have made use of a newly-developed scientific method by which for the first time ever the heights of the mountains could be accurately determined. However he did it, his method seems to have tended to generate some sort of systematic error and in fact the values recorded are ca. 1/6 high. Aristotle in fact uses just the argument that Dikaiarchos later did: that the fixed stars visible to an observer moving north or south on the Earth change. Fritz Wehrli argues that Dikaiarchos referred to the difference in rising times apparent to one going east or west.
