Bellarmine Jug
Late 16th century.

At this period, wines and beers were drawn from barrels into
bottles of stoneware or leather. This type of stoneware bottle
(salt-glazed) was made in the Netherlands and incorporated a
stamped image of Cardinal Robert Bellarmine (1542-1621).
This man was a bitter opponent of the Dutch Reformed Church and
so it was common for Protestants wishing to insult him to smash the
jugs!
These vessels were also frequently used as 'witch bottles'. This
entailed filling the jug with certain articles, sealing it and
burying it. This was done in order to deflect a witch's curse. Many
of these witch bottles have been discovered.
