CLAYDON, a chapelry in that part of the parish of CROPREDY which is in the hundred of BANBURY, county of OXFORD, 6 miles (N.) from Banbury, containing 252 inhabitants. The village is the most northern in the county; a small spring which rises in it has the peculiarity of emitting the largest quantity of water in the driest weather. The inhabitants enjoy the privilege of sending fifteen children to the free school at Farnborough, in Warwickshire. Here are found the pyrites aureus, or golden fire-stone; also the asteria, or starstone, called by Gesner " sigillum stella," from its use in sealing: in splitting some of these, the figure of a rose is plainly discernible in the centre.
