Can I get a grammatical breakdown of "通りゃんせ"?


So, I recently learned that there's this song called
[「通りゃんせ」](http://ja.wikipedia.org/wiki/%E9%80%9A%E3%82%8A%E3%82%83%E3%82%93%E3%81%9B),
which I guess would be familiar to all of you who have lived in Japan.

The grammatical form "通りゃんせ" (and later in the song, "[下]{くだ}しゃんせ") is
completely unfamiliar to me. The Japanese Wikipedia article for the song gives
通りなさい as a translation, which is good to know, but I would like to know more
about this form. I figure that it is either archaic or at least non-標準語,
judging from the use of じゃ as a copula and 通しゃせぬ as the negation of, uh, I
guess 通す or some related verb.




"通りゃんせ" is a colloquial contraction of "通りやんせ", which is masu-stem(連用形) of
"通る"="通り" with imperative form(命令形) of "やんす"="やんせ". Also, 下しゃんせ is "下す" with
"やんす".
