If the Germanic peoples got their fuþ*ark from the Etruscans (or whomever) why did they change the order so radically? They did assign much magical powers to the runes, so presumably they re-ordered it for reasons of their own, but what were those reasons?

The other alphabet that I referred to above (in flat mode, below in threaded) was the Irish tree alphabet (BLNFS...); the letter names were the names of trees that had some characteristic that was representative of a certain month (cf. Graves, Robert The White Goddess) The order was from the winter solstice on.

*For those of you who with thorn challenged computers, such as Macs, that character *was a thorn and not an eff-aye ligature or other curious character.
