Prothalamion revisited

[Tiger the Lion]

Sweet Themmes, run softly
for the day is not long
to close, and she
not among
those thronging on your banks,
though the hour draws near
where I end my song.

Hey Achebe. With a little patience I found the original, which was new to me. So thanks for that. There is a subtlety to the rhymes that I really enjoyed. Especially the slanted "among" dead in the middle.
Cheers for the read.
