Formerly it was the custom to hold a large supplementary rite (Eyu) for an important man [upon his death]. This would be performed as soon as possible after the normal rites, but might be delayed up to six months or perhaps a year.
When the decision to perform the ceremony was made, his heir would send word for all the dead man's relatives to meet together and fix their contributions of livestock (chiefly goats) to the celebration. Large numbers of these were necessary to make the eyu a big occasion.
