Diobol - Ptolemaios III

Ptolemy III Euergetes inherited a kingdom already dominant in the eastern Mediterranean and promptly made it larger, launching the Third Syrian War in 246 BC and driving deep into Seleucid territory — by some ancient accounts reaching as far as Babylon and Bactria before domestic unrest in Egypt forced his withdrawal. The bronze coinage of his reign was issued on the Ptolemaic reduced standard established under his predecessors, part of a deliberate policy of monetary isolation that kept foreign coins from circulating freely within Egypt.
