In case you are interested if not already familiar, here is a link to a nice automated table on the Elements as well as the website for Tycho Brahe & Ole Rømer - Castle, Observatory in Denmark. Thought the examples of the old property layout was interesting geometrically, which is now all gone - citified.
There is also some 3-d (need software - which is linked) examples of old instruments of measures etc.
