"At the moment I am having a closer look at the Brouscon circular tidal diagrams. To use them is, as far as I can see, not so difficult but what I want to know is how he constructed these tide tables" For those who have a copy, there are examples of these on page 19 of Cartwright's "Tides: A Scientific History". Since thy date from 1543, I think you can count on these being a very simple representation of tidal behavior. -FER 42.0N 87.7W, or 41.4N 72.1W. www.HistoricalAtlas.com/lunars
