Meaning of せん in そのすべてに感謝せん


> 大地の精霊よ  
>  イシの村にもたらす恵み  
>  そのすべてに感謝せん

I am wondering if this is perhaps a shortened version of an expression like
感謝の言葉もありません or something like that?

I've tried looking in jisho for せん but it is still unclear to me.




This せん is not a negation. そのすべてに感謝せん here means "Let us thank all of them".
It's そのすべてに感謝しよう in modern Japanese.

せ is the 未然 (irrealis) form of す ("to do") in classical Japanese, just as し is
the 未然 (irrealis, pre-nai) form of する in modern Japanese. ん is a shortening of
む, which is a volitional auxiliary in classical Japanese.

  * [Is there a difference between んがため and ために?](https://japanese.stackexchange.com/q/5396/5010)
