Turkish Olive Oil Wrestling

I knew that the ancient Greeks once anointed themselves with olive oil prior to athletic contests. I hadn't realised that not only do Turkish wrestlers still practice this but have named their sport after Olive Oil. Before entering the ring the combatants pour two pitchers of olive oil over themselves. This makes it hard to grip each other. Some say the sport dates back to the Babylonians as evidenced by evidenced by 4600 year old figures of people wrestling with olive oil containers on their heads.
