In historical time, Central Sulawesi highlanders have performed circle dances and accompanying songs (in Uma raego) at all major precolonial rituals.
They were ritual procedures, among other things, to augment the agriculture and human fertility of highland families.
[2] In the dances there was close physical contact between men and women and this was something European missionaries objected to.
[4] Captain Boonstra van Heerdt, a dutchman records the raego from Kulawi, Lindu and other places.
[3] While the children were confined to heal and fed only rice porridge after the puberty rites, adults celebrated just outside the temple singing and dancing moraego every night.
