I have read somewhere (forgot where) that you can tell how a person died by looking at the monument. If both legs of the horse are on the ground then the person on the horse did not die related to battle, if one leg of the horse is in the air then the person was wounded in battle and if two front legs of the horse are in the air then the person died in battle. I do not know if there is truth in that but it is interesting to look around Zagreb and notice where are the horse's legs :)
