The midwife also took charge of the naming ritual. The baby was carried out into the courtyard of the house to be bathed in an earthenware tub placed on a layer of rushes. Water was sprinkled on the child’s mouth, chest, and head, while the appropriate incantations were made. Then the midwife washed the baby all over and recited the prayer to keep away evil. In addition, a boy was presented to the Sun, with a prayer that he might acquit himself well as a warrior.
