Gui food vessel Yuan Dynasty
this vessel 簋 is a type of bowl-shaped ancient Chinese ritual bronze vessel. Used to hold offerings of food, probably mainly grain, for ancestral tombs. As with other shapes, the ritual bronzes followed early pottery versions for domestic use. And in later art shaped in metal, pottery as well as stone. The shape changed somewhat over the centuries. Mainly of circular form (seen from above), with a rounded, wide, profile or shape from the side, standing on a narrower rim or foot.
