Three more seals done - some of the Celtic knots.

The Horned Triskelion is often attributed to the Celts, but it was used thousands of years before that in the stone age. Modern interpretations usually depict legs instead of coiled horns.

(As you can see I'm still working on the tree of life, but when that is done the Celtic/Pagan subset will be complete for now)

These images are from the portfolio of Wolfgang Braun, who has spent 50 years reconstructing the castles using a combination of factual evidence and fantasy extrapolation where things were unkown about them.

Fields can be a bit difficult to get right. This surprises a lot of people, but it's true.

Here are a few thoughts on the shape they take:

• In a medieval field system there were quite often major and minor divisions in the UK. One large field area marked by a hedge or stone wall, with strip fields that were the responsibility of different tenants, and from which the stones were cleared to either side, causing ridges to build up between the strips - strip lynchets.
• Fields tended to follow the contours around hills, and align themselves with a narrow end to the river, so that even if their boundaries were straight the grid they formed warped around these features.
• Even in extremely flat areas the presence of a river or a road will disrupt the gird.
• Not many places on Earth show boundaries that are exactly East-West or North-South. The grid, if there is one, can be aligned in any direction depending on which direction allows for the most convenient layout, or the greatest area put to the plough.

These are only general rules of thumb. I'm quite sure these things are totally contradicted in many places that aren't England, but they hold true right here where I live.
