Does the verb 死ぬ has a 死ぬる form?


I have come across a conjugation of 死ぬ verb which I've never heard before. It
is 死ぬる, I have heard it in a TV show, you can see the relevant part in [this
video](http://www.youtube.com/watch?v=WtNHr3OuNhA).

Is this a depreciated form? If so, what meaning does it have? Can you use it
in an example sentence?  
Or is it just a made up conjugation for making rhyme in the poem?




In classical Japanese, 死ぬ is an irregular verb (ナ行変格活用動詞). Its principal parts
are as follows:

  * Irrealis (未然形): 死な〜
  * Continuative (連用形): 死に〜
  * Predicative (終止形): 死ぬ
  * Attributive (連体形): 死ぬる
  * Realis (已然形): 死ぬれ〜
  * Imperative (命令形): 死ね

The difference between the predicative and attributive forms is roughly
analogous to the difference between 〜だ and 〜な for the adjectivial nouns in
modern Japanese. Here is an example of 死ぬる as used in classical Japanese:

> 死【し】ぬる子は 眉目【みめ】よし
>
> The face of a dying child is always beautiful.
