There's certainly evidence in the text that he was physically unremarkable. When they go to arrest him in John, he has to be pointed out to the guards doing the arrest. Why would the text have such a passage as this if he were a statuesque, Euro-Jesus (as carved) as opposed to an average-sized Middle Eastern Jew with sun-baked skin and short, curled hair, as NatGeo demonstrated was likely many years ago...?

What's more, current science has evidence that certain social misfits are better at divining truths about human nature. To my mind, people who were fit to be warriors and laborers in ancient societies wouldn't have found themselves in the ranks of the scholarly and wise, so perhaps all these thinkers are remembered as short because they couldn't do the manly work, thus they were ostracized to some degree, and managed to outlive and outshine the meat heads, as it were...just a thought.

Maybe it's a bit reductive to say that. After all, Euripides had a military career. Still, short men throughout history have been regarded as less desirable, as men go, hence why we have such a term as the Napoleon Complex. It makes sense that the smarter short ones would suffer as outcasts on some level and go on to leave behind some profound observations about the world in which they were living...to me at least.
