Votive offerings are common and in display in Greek Orthodox churches, and the medal of Olympic champion Spyridon Louis, is among the offerings to Saint George in the monastery. Spyridon Louis was a 24-year-old Greek water seller who became the hero of the 1896 Games when he won the 40,000m marathon race. This was the event the Greek hosts wanted to win more than any other due to its great historical significance. BTW, in case you have not come across it, a water seller is a profession that existed before the advent of centralized water supply systems. A water carrier collected water from a source (a river, a well, water pumps, etc.) and transported or carried containers with water to people's homes
