Knots inter-twine

This rather perfect piece of moulding over this window in Hanley shows a wonderful series of interlocking 'Stafford Knots'.
I thought it might be nice to end the old year with a reminder of the symbol of Staffordshire.

The building belonged to the Potteries Water Board in the nineteenth century, and the crest on the left is actually the PWB's.
The crest on the right is that of the then Borough of Hanley.  Oddly, its heraldic animal (you can see it over the crest) was a camel.
