In our occasional series, I Didn't Know That, tonight Karyn talks to Brent Davis from University of Melbourne about a stone that helped unlock the secrets of hieroglyphs.

Dr Davis is a specialist in many things antiquity-related, including ancient languages and scripts, Philistine Archaeology and Archaeology of ritual and religion. He chats to Karyn about the process of understanding the Rosetta Stone.
