This vessel resembles a pilgrim’s bottle, with loops on its shoulders for attachment to a cord or strap. Exceptionally, however, a hollow, free-blown image of Jesus crucified (Corpus Christi) is attached to the flask. His body could thus be filled with wine or any other liquid poured into the bottle. The function of this unusual glass is not known. Could it have been used in church celebrations of the Feast of Corpus Christi?
