The head of the Gorgon is depicted in the white centre of the brown section, and there is another head on the other side of the "aegis", shown projecting at the left. This may be Phobos, the personification of fear, who is often said in Greek literature to decorate the shields of heroes, and who Homer said appeared on the "aegis". The pose and these details compare closely to a cameo in the Metropolitan Museum of Art, New York, which handles the body rather more effectively (see gallery). In New York one of the heads is interpreted as "a wind god, perhaps intended as a personification of the summer winds that brought the corn fleet from Egypt to Rome and so an oblique reference to Augustus’s annexation of Egypt after the defeat of Mark Antony and Cleopatra at Actium in 31 B.C.".
