Flodden is based on Sir Walter Scott's epic poem "Marmion", which is about the Battle of Flodden Field - the largest battle between English and Scottish forces.

Each set of connected line segments represents a word in the poem, randomly distributed.  The lines started as red or blue according to the proportion of troops, with the dead (represented as black) apportioned according to the casualties on each side.

The Scottish lines are longer than the English lines, to represent the distinguishing weapons – Scottish pikes vs English bills.
