This is an image that a friend of mine sent me some days ago. What you see is a couple of lead sling bullets from ancient Greek warriors. The one on the left side has engraved a thunderbolt, sign of ancient Greek god Zeus. The one on the right side though, has engraved the word "ΔΕΞΑΙ", which means more or less "Take that". Other sling slogans include "ouch" and "for pompey’s backside!"
