In African cultures, African traditional religions the ritual of pouring libation is an essential ceremonial tradition and a way of giving homage to the ancestors. Ancestors are not only respected in such cultures, but also invited to participate in all public functions (as are also the gods and God). A prayer is offered in the form of libations, calling the ancestors to attend. The ritual is generally performed by an elder. Although water may be used, the drink is typically some traditional wine (e.g. palm wine), and the libation ritual is accompanied by an invitation (and invocation) to the ancestors, gods and God. In the Volta region of Ghana, water with a mixture of corn flour is also used to pour libation.
