Does anyone know the significance to Druids of the Number 6?
Well, perhaps I can shed some new light on the problem as this question should, to my knowledge, be answered using druidism's connections to ancient Pythagoreanism that much elaborated on the signifficance and sacred use of numbers (both in geometry and algebra). See the topic Pythagorean Druids
here.
Six (in Pythagoreanism and classic Hermeticism) is the number denoting the Circle (and in Western Hermeticism and Alchemy also Heaven). Why six?
"Six around One" goes the line (only six equal circles fit around an equal circle). You may see for yourself: try to arrange some oranges around a single orange so that their rims all touch each other, you will find that six is the number that fulfills this condition. You may also draw it: draw one circle over another so that their rims run through each other's centres and then connect the points of tangencies to form a rhombus (two equilateral traingles). The figure "around" the rhombus is vesica piscis, an almond-shaped figure, often used in Celtic patterns to form triquetras; in Celtic illuminated manuscripts Christ is often seated within a vesica. Now if you add a third circle on the other side of the forming circle you will be able to see
six equal equilateral traingles, and the points of tangencies will form a perfect
hexagon. If you draw circles using the points of tangencies as their centres you will produce always only six such circles. So, in fact, everything in the Cicrle is about the number
six.
The Biblical theme of six around one is actually a very fine one: it shows how the order of all Things is arranged around One (even in the story of the world being actively created in six days with the central one day of passiveness).
And the signifficance of the Circle in druidism, an indeed in all Indo-European cultures, you perfectly know of. If all things are viewed as perpetual, circular, spiral in the Celtic world, then six will be the number of the fulfilling of creativity, the Celtic horn of abundance, for it is in the process of forming the hexagon that the awenyddic triquetra (like the triskele, the symbol of all worlds and elements combined, and the perfection of druidic skills) is produced.
For a fine and simple reading on this I recommend the fabulous series "Ancient Science" by Wooden Books, to be found
