CIRCA 14-80 A.D.

Vessels of this form seem to have originated in the Tiberian-Claudian period, and enjoyed a brief but widespread popularity until around 80 A.D. Whitehouse notes they are "usually found in relatively rich graves" in Italy and the surrounding Western provinces (1997, p. 167). See no. 293 in this publication for a very similar semi-opaque white bottle, but with deep blue twin handles.
