How to parse the proverb [艱難]{かんなん}[汝]{なんじ}を[玉]{たま}にす?


I found this particular proverb on WWWJDIC when I looked up for なんじ :
[艱難]{かんなん}[汝]{なんじ}を[玉]{たま}にす. It is translated into English as: Hardship makes
the man.

How do we parse the proverb? I know 艱難 {かんなん} means "hardship". But 汝 {なんじ}
means "thou" (archaic 'you') so what nuance does it contribute when suffixed
to 艱難? And does 玉 {たま} mean jewel or actually refer to the [family
jewels](http://www.urbandictionary.com/define.php?term=family%20jewels)? And
what about にす, is it an archaic verb, or simply abbreviation of にする? How are
all these in the end summed up as "hardship makes the man"?




The sentence is classical Japanese, not modern Japanese, and should be parsed
as such. I analyse it as follows:

> 艱難 汝を 玉に す  
>  kannan nandi-wo tama-ni su  
>  hardship thou-ACC jewel-LOC make  
>  _Hardship will make you into a jewel._

In classical Japanese, the subject of a main clause is usually not indicated
by a particle. In a typical sentence, the main verb will be in the terminative
form (終止形); the classical form of the modern verb する is an s-stem irregular
verb (サ行変格活用動詞) and its terminative form is just す. する is its attributive form
(連体形).
