It’s known as Jultagi. The direct translation is “rope riding”. It’s an ancient form of entertainment that some say was seen during the time of the three kingdoms (57 BC to 668 AD).
It became popular during the Joseon Dynasty (1392 to 1897) and can still be seen during festivals and public holidays in South Korea today.
This man was performing in Sydney though.
My son and I were at a Korean festival in Darling Harbour many years ago. We watched him bob up and down, sit, and turn on his swinging rope above us.
For Becky’s Past Square challenge during October.
