Late Old Babylonian period (c. 2000-1600 B.C.E.), probably time of Hammurabi (reigned c. 1792-1750 B.C.E.)
These female figures are lammas. A lamma is a generally anonymous, benevolent female deity in human form. These lammas have their hands raised to the heavens and are wearing flounced dresses and horned helmets: a standard appearance for this kind of figure in Babylonian art and seals.
