Cantharus

The cantharus was a large cup with two handles and resting on a foot.

It was part of the argentium potorium and it was widely used.

The picture below shows a cantharus  from the Moregine treasure depicting a priestess of the Isiac cult while she is feeding a grape to a cock on an altar. On the right is a detail from the same cantharus showing a table with ministerium on it.
