A Vast, 430-Year-Old World Map
I'm always surprised at the awful artistic skills of maps during this period. If you look at the details, you can see how wobbly and uneven the simplest of lines and curves are. It seems odd because on the very large scale it would appear as if some sort of compass and other devises were used, but simple lines consist of overlapping strokes, erratic and handwritting that refuses to be consistently centered, and child-like scribbles for trees. For a 20 year effort, it seems careless and lacking in even rudimentary art skills. But this seems tn be every map from the period, not just this one.
