These small glass masks represent Dionysius, Greek god of wine and ecstasy. The Dionysian cult had many adherents in Egypt at the time of the Ptolemaic kings.
Dionysius appeared often in Greek theatre with its masked actors. Theatre was very popular throughout the Hellenistic world. Scenes from plays were often depicted on murals and vases. The glass theatre masks probably come from a luxury case or crate to keep jewellery in.
