Classical form of 落{お}ちる


I read in a haiku written by
[Bashō/芭蕉](https://en.wikipedia.org/wiki/Matsuo_Bash%C5%8D)
([source](http://www.takase.com/JapaneseCalligraphy/Haiku/HaikuSource01.htm) -
see my addendum at the end of the post) :

> をちこちに
>
> 瀧{たき}の音{おと}聞く{きく}
>
> 落{おち}葉{ば}かな

My translation :

> From far and near, hearing the sounds of the waterfall(s), ah, the fallen
> leaves...

My question deals with the word 落{おち}葉{ば}, derived from 落{お}ちる (to drop, to
lose) ? I noticed the poet played with the sounds /ochi/ in **をち** こちに and in
**落{おち}** 葉{ば}.

Moreover, I know that Classical Japanese words beginning with を have dropped
the initial /w/, giving words beginning with /o/, like をんな > おんな.

**Hence my questions :**

  1. In Classical Japanese, did the verb 落{ちる} start with お (おちる) or with を (をちる). Or did the word 落{おち}葉{ば} begin with お (落{おち}葉{ば}) or with を (落{をち}葉{ば}) ?
  2. Is there any online dictionary giving this information ?

Any help would be appreciated !

_addendum_ : I read this haiku for the first time in a French anthology :
"Bashō, Cent onze haiku"(=Bashō, 111 haiku), by Joan Titus-Carmel, page 108.
Titus-Carmel's translation : "De loin et de près s'entend le bruit des
cascades - la chute des feuilles !". The Japanese text given by Titus-Carmel
contains the word 落葉. Alas, the author doesn't give any further details about
his source : nothing but a simple "the haikus translated in this book are
taken from Bashō's works" on the last page.




I don't know if @l'électeur's comments were rhetorical or otherwise, but I
only find the poem as 若葉 (not 落葉) and written by 蕪村 (not 芭蕉). Here's [a more
reliable reference from
青空文庫](http://www.aozora.gr.jp/cards/000305/files/47985_41579.html)

It might not be relevant any longer, but the historical spelling for the お in
おちる was just お, and not を, as already answered in the comments (e.g. 大辞林: お・ちる
(動タ上一) [文] タ上二 **お** ・つ or also in 大辞泉, which is accessible via
<https://kotobank.jp/>).
