Glass portrait head of a woman, Roman, 1st half of 2nd century C.E. Height.: 7 ½ in./19.1 cm. On view in Gallery 168, Metropolitan Museum of Art, New York. (via The Met)
This portrait, in glass imitating rare and valuable lapis lazuli, was made by pressing the glass into an open mold. It probably represents the goddess Juno (Greek Hera), the consort of Jupiter Capitolinus, and must have been set up in either a public temple or a rich private sanctuary.
