At the end of each Shabbat, Jews customarily perform a small ceremony known as Havdalah to mark the beginning of the new week.  During the recitation of this prayer, participants invoke their various senses by smelling spices or other aromatic sprigs which are stored in small ornamental boxes. As far back as the 12th century, spice boxes were used for this purpose and today remain among the most common form of Jewish ceremonial art.
