Looking at some medieval paintings I noticed that there are sometimes people "looking elsewhere" even though they take part in an important event and would be expected to pay attention:
Is there a significance to this? Or is it just a question of style ? (to add some dynamics for instance)
I read somewhere than in the case of religious paintings of Mary and Jesus, he was often looking away to symbolize the future, but this could hardly be the case for the normal (although probably important) people in the illustrations above
