it's so funny how square everything became depicted because of the colonnella, even cavalry. it's an easy art technique but however disciplined these formations could be they would appear swirling on the field, the shuffle of arquebusier (mousquetaire) and support around the pikes, the cavalry performing caracole and otherwise charge-retreat-repeating, demi-lancers and harquebusiers attempting to get between and disrupt formations at every opportunity---ultimately a heap more dynamic and interesting to watch than the 18th century squares depicted in the same style but were actually maintained for most a battle
