So here is a different version of that oath:
"There is a certain grandeur in the oath of Rustringen recorded in an old thirteenth-century document:
'We Frisians will defend our land with five arms: with sword and buckler, with spade, fork and spear, whether the tide be ebbing of flowing. We will fight day and night so that all Frisians may be free, both now and hereafter, as long as the wind blows through the clouds and the world remains.'
OK, and now to find the original Frisian text.
Not found the original text yet, but I found something close and nowhere else then on the Taaldacht site (that gives me hope Van Renswoude can actually answer my question):
Ak skilu wí úse lond wera mith egge and mith orde and mith thá brúna skelde with thena stápa helm and with thene ráda skeld and with thet unriuchte hęrskipi.
(Ook zullen wij ons land verdedigen met zwaard en met speer en met het bruine schild tegen de hoge helm en tegen het rode schild en tegen de onrechte heerschappij.)
Also we will defend our land with sword and spear and with the brown shield against the high helmet and against the red shield and against the injust lordship/rule
And it is indeed a text from Rüstringen:
In the OLB the Scheldt with all it's fancy letters is actually spelt as SKELDA.
Saendfal nw Skelda wrdon Stjurar
O.E. scield, scild, related to sciell (see shell), from P.Gmc. *skeldus (cf. O.N. skjöldr, O.S. skild, M.Du. scilt, Du. schild, Ger. Schild, Goth. skildus), from base *skel- "divide, split, separate," from PIE base *(s)kel- "to cut."
Here's the explanation for the name of the Scheldt:
The Scheldt (Dutch: Schelde [ˈsxɛldə], French Escaut) is a 350 km long river in northern France, western Belgium and the southwestern part of the Netherlands. Its name is derived from an adjective corresponding to Old English sceald "shallow", Modern English shoal, Low German schol, Frisian skol, and Swedish skäll "thin".
So, does anyone have an idea if the word Scheldt could actually be named after the word for shield?
Sceald says shallow but shoal is more like a divide, maybe even a split or seperate, usually a shoal is some kind of sandbar that can divide the water.
We have places called shoal everything, Shoalhaven, I know what a shoal is. Plus the shoals in Atlantis, I'm always looking for shoals...
A shoal, sandbar (or just bar in context), or gravelbar is a somewhat linear landform within or extending into a body of water, typically composed of sand, silt or small pebbles.
Kind of sounds like she'ol too.
So, I'm just wandering whether the word for Scheldt could actually be shield and in a newer form is actually shallows but used to mean shield, cut off, divide - like shield yourself from something, put up a barrier context.
Otharus, do you have an opinion on that one?
