explain the sinificance of the natual ritual of the funeral in Antigne

Funeral rights were pretty important to the ancient Greeks. They didn't believe in the concept of Heaven and Hell in the classic Judeo Christian way. It was important, however, to be burried which explains Antigone's insistance that her disgraced brother Polynices to rot above ground. The unburried were thought to be doomed to wander by the river Styx, the entrance to the Underworld. They would wander the river for eternity; their souls could never be at rest. Denial of burrial meant not only an insult to the body but a damnation of their soul.
