The hexagram at the center of this platter suggests a Jewish connection, as do its six shallow compartments. If it is a traditional Passover plate, these hold the ritual foods discussed at the holiday’s meal, or seder. But seder plates usually have Hebrew inscriptions identifying each of the symbolic foods. This plate’s blue-and-white glaze and pattern of vines, blossoms, and birds perched in branches are inspired by Chinese porcelain and give no hint about the dish’s purpose.
