Incantation bowls were used as amulets to protect the house and its inhabitants. Some bowls, such as the present example, were used to arouse or restore love between a couple. The bowl would be buried upside-down in order to trap the evil spirit beneath.
Although not unique, it is very rare to find an incantation bowl that invokes the powers to help salvage the love between a married couple. One of the angels invoked is a Jewish angel, Nuriel, the Light, whose name is associated with love. It is mentioned in an ancient Kabbalistic source that Nuriel's name be inscribed on any amulet regarding love, as he brings the divine light to earth to spark the hearts of lovers.
