I thought that this story was interesting.
“JERUSALEM – Archaeologists digging at the purported biblical home of Goliath have unearthed a shard of pottery bearing an inscription of the Philistine’s name, a find they claimed lends historical credence to the Bible’s tale of David’s battle with the giant.
While the discovery is not definitive evidence of Goliath’s existence, it does support the Bible’s depiction of life at the time the battle was supposed to have occurred, said Dr. Aren Maeir, a professor at Bar-Ilan University and director of the excavation.
“What this means is that at the time there were people there named Goliath,” he said. “It shows us that David and Goliath’s story reflects the cultural reality of the time.” In the story, David slew Goliath with a slingshot.”
What I would be particularly interested in is finding out just how big the average man was then compared to Goliath. Humans are a little larger now than we used to be it could be that Goliath was a true giant and would be seen as such now as well as then. Or alternatively within a modern context he might be just average.
