the basis for the introduction of saxon mileposts was the cartographic work of the pastor, adam friedrich zürner, from skassa. zürner had prepared a map of großenhain, which attracted the attention of augustus the strong. after further cartographic work, the prince elector gave him the task on 12 april 1713 of: ""recording districts, including the lordships, manor estates, towns, villages and the like, on geographic maps"" (original: ""aemter samt denen darinnen befindlichen herrschaften, rittergütern, städten, dörfern und dergleichen mehr in mappas geographicas bringen""). this entailed the topographic survey of electoral saxony. in addition to the heartland, it covered the electoral saxon parts of the counties of henneberg and mansfeld, the schönburg estates, the estates of the albertine branches of saxe-merseburg, saxe-weissenfels and saxe-zeitz as well as the two lusatias.
