ohsoromanov:The Blacas Cameo showing Augustus wearing a gorgoneion on a three layered sardonyx cameo. The Blacas Cameo is an unusually large Ancient Roman cameo, 12.8 cm (5.0 in) high, carved from a piece of sardonyx with four alternating layers of white and brown. It shows the profile head of the Roman emperor Augustus and probably dates from shortly after his death in AD 14, perhaps from AD 20-50. -- source link
