Sacrificial tripod

"A sacrificial tripod is a three-legged piece of religious furniture used for offerings or other ritual procedures. As a seat or stand, the tripod is the most stable furniture construction for uneven ground, hence its use is universal and ancient. It is particularly associated with Apollo and the Delphic oracle in ancient Greece, and the word "tripod" comes from the Greek meaning "three-footed"." - (en.wikipedia.org 10.03.2020)
