As far as I understand the navigator in the early
times used widely diagramatic methods.
The bias in favor of calculation came only after
tables ,like traverse tables were made available to him.Calculations were made
even more easy after the tables of common logarithms had been calculated.This
happened around 1625-1635
What I don't understand: do you mean that there
has been a move back to using diagrams after all these tables were
available?
Thanks
