A Romano-Egyptian spherical bead made from polychromatic glass. The bead features a red matrix, interspersed with a dark blue band. Within this band are four faces, their delicate faces made from white glass and facial features defined in black. Each face is surrounded by a white roundel. The bead is pierced vertically for suspension. It is believed that the faces depict the mythological Gorgon; the undulating black lines of her hair representing the unruly snakes that framed her face.
Date: Circa 1st century BC – 1st century AD
