A group of three brown glazed bowls with impressed decoration
Tran-Le dynasties, 14th/15th century
Each with a delicately foliated rim and impressed decoration across the well: the first bowl showing alternating cloud and floral panels around a cloud roundel and the second bowl impressed with a lotus pod medallion surrounded by flowering plants, five spur marks appearing in the dark brown glaze across both wells; the third bowl impressed with alternating peony and prunus flowers and the abbreviated Chinese characters guan yao at the center surrounded by an unglazed firing ring within the pale brown glaze layer; the glaze on all three bowls continuing onto the exterior walls, stopping unevenly above each foot ring and recessed base.
