Libationer

That the libation was the all-important element at this ceremony is further illustrated by the fact that a regular attribute of Isis as the chief officiant thereat is ḳbḥ∙ t “the (female) libationer” (id., pp. 13, 55, 56).

However, on special occasions there may be an elaborate and complex ritual and more than one libationer, usually a leading or chief libationer and an assistant or a number of assistants.

The “libationer” may also solicit the spiritual presence of humans who are alive although not physically present at that particular enactment of the ritual—people who are known to share the aims of the librartioner and would therefore support the petition(s).

Harming other people or bullying them because the libationer is in a position of power or has connexions with people in power is also proscribed (60, 92).
