Re: Non-French drawing traditions?
I think that there seems to be just one classical Western approach to drawing since the Renaissance. The French were working from the forms established in Italy at the time of Raphael, Leonardo and Michelangelo.
Printmaking spread that approach quickly through Europe. The Northern European masters seem to me a seamless part of the same tradition. Linear perspective was High Science then, as Alberti's book demonstrates.
No one seemed to have any new ideas until Pablo and Georges gave us Analytical Cubism. The late nineteenth century was influenced by the Japanese tradition but synthetically I think.
I would be pleased to be corrected on my thinking.
