The Olympic Games ceremonies of the Ancient Olympic Games were an integral part of these Games; the modern Olympic games have opening, closing, and medal ceremonies. Some of the elements of the modern ceremonies harken back to the Ancient Games from which the Modern Olympics draw their ancestry. An example of this is the prominence of Greece in both the opening and closing ceremonies. During the 2004 Games, the medal winners received a crown of olive branches, which was a direct reference to the Ancient Games, in which the victor's prize was an olive wreath. The various elements of the ceremonies are mandated by the Olympic Charter, and cannot be changed by the host nation. This requirement of seeking the approval of the International Olympic Committee (IOC) includes the artistic portion of opening and closing ceremonies.
