A fine Ancient Roman glass unguentarium, formed from translucent pale blue glass. The bottle takes the typical form of a small, domed body tapering into a long, circular neck which culminates in an everted rim. The base is slightly concave. Earthly encrustations to the surface. Unguentaria were amongst the most common objects of Roman blown glass: produced in large numbers, they were items of everyday use for keeping expensive perfumes and cosmetic oils. The small body and mouth were ideal for slow, careful pouring, while glass was preferred for holding liquids, due to its non-porous, non-absorbent nature. Measurements: (circa) H 8.7cm x W 2.6cm Provenance: Ex London Art Market, acquired 1980s-90s.
