I've always figured that the sallow, effeminate depictions of Jesus weren't right. After all, the guy was a carpenter in a time when everything was done by hand.
He'd have had big, strong, workman's hands and arms. He'd have had a face that was sharp-featured like the image on the Shroud of Turin -- something to set him apart.
He apparently met the expectations of those who though of the Messiah as a military conqueror -- meaning he was probably not smaller than average, possibly larger -- he certainly had whatever it is about natural leaders that fairly shouts, "follow me."
Maybe. But there is no Biblical evidence whatever to support the myth that he spent his life (after age 12) pounding nails.
