Sounds interesting. I never would have assumed double-entry bookkeeping went back that far. Any good book suggestions?
It describes changes that happened in war, mining, shipping, trade in (mostly western) Europe in the last decades of XV century. The common theme is finance and it includes a chapter on how bank houses became bigger and could secure much bigger loans (which allowed bigger states to wage wars, or rich individuals to bid for top titles ;)).
Fun read.
One learns every day :) I will be more careful about this when writing centuries in English the next time.
