GASTROMANCY, or GASTROMANTIA, a kind
of divination practised among the ancients by means of
words coming or seeming to come out of the belly.
The word is Greek, γαστρομανία, composed of γαστρ,
belly, and μανία, divination.
There is another kind of divination, called by the
same name gastromancy, which is performed by means
of glasses or other round transparent vessels, within
which certain figures appear by magic art. It is thus
called, because the figures appear as in the belly of the
vessels.
