It is impossible to adapt the
later sacrificial theory, as it appears in the next period, to the Rigvedic texts,
and it is clear that at this time the sacrifice was less elaborate than it
became; but there is abundant proof that already the Soma sacrifice in
particular had been elaborated, and that the labour had been divided
among several priests, the chief being the Hotội who recited the hymns and
in earlier times composed them, the Adhvaryu who performed the manual
actions to the accompaniment of           prayers and deprecations of evil,
the Udgātņi who sung the Sāman chants, and several assistants, the number
seven being found quite frequently in the Rigveda.
