Heí Phyllis,
My version had a few hints of Middle English (rather than OE) e.g. 'spithra' & 'spute'
and uses some "poetic license"; e.g. although 'yntse' appears in Bosworth/Toller, it is there as a Latin derived noun, (from which mod. Eng. small things, such as "inch" and "ounce" are obtained).
Can such a noun be used as an adjective? and if so can a word be "invented" for the sake of poetry?;
i.e. 'winsig' doesn't appear to exist, but it would fit better than 'winsum'.
(I wonder how purists will react);
Yntse winsum spiðra, up-clomb se wæter spútan
Dúne com se regn, ond spiðran (he) út-gewæscede
Út com seo sunne ond (e)allne regn (heo) up-gedrigede
Swa yntse winsum spiðra, se spútan ongean up-geclomb
You're welcome to use, edit or ignore the above, at your will
Good luck!
Brian
