Why a Macedonian king put a Greek shield in his tomp?

One from the most important archaelogical found in Vergina was the Ivory Shield that was found in pieces in Philip's tomp.
The arduous process of restoration took several years(14 years after a question to the quider).It is a unique masterpiece of the 4th century.
Give your attention in the the external ring of the Philips Shield and the Symbol of the Hellenism, the known Hellenic Key
