Three mounted knights in armor for particular types of tournament: course with full arm-armor (garde-bras) with great helm (heaume), course with round shoulder armor (rouelle) and small shield (targe), and a joust with coronet spear.. In the course, the knight aimed his lance at a particular spot on the opponent's breastplate - when this button was hit, a metal plate was shot into the air above the knight. Note the lance tips of the coursers, and the lance with coronet point of the joust knight at right..
