A few drawings and a 3D rendering of some of Goliath's weapons to be used as reference in The David Story graphic novel series. Designs are based on information from the Bible and bronze-age archaeologists' findings from the middle east.
1 Samuel 17:4-7
Then a champion came out from the armies of the Philistines named Goliath, from Gath, whose height was six cubits and a span. He had a bronze helmet on his head, and he was clothed with scale-armor which weighed five thousand shekels of bronze. He also had bronze greaves on his legs and a bronze javelin slung between his shoulders. The shaft of his spear was like a weaver’s beam, and the head of his spear weighed six hundred shekels of iron; his shield-carrier also walked before him.
