it fell, after being photographed in 2007, but was re-erected again a few years later by the owner of Dunachton Lodge. The symbols are found on some of the extremely rare survivals of Pictish jewellery, such as the pair of silver plaques from the Norrie's Law hoard found in Fife in the early 19th century, and the Whitecleuch Chain. The symbols are also sometimes found on other movable objects like small stone discs and bones mostly from the Northern Isles. Simple or early forms of the symbols are carved on the walls of coastal caves at East Wemyss, Fife and Covesea, Moray. It is therefore thought likely that they were represented in other more perishable forms that have not survived in the archaeological record, perhaps including clothing and tattoos. Some symbols appear across the whole geographical range of the stones while, for example, six stones with the single symbol of a bull found at Burghead Fort suggest that this represented the place itself, or its owners, despite other examples appearing elsewhere. Exeter analysis A team from Exeter University, using mathematical analysis, have concluded that the symbols in the Pictish image stones "exhibit the characteristics of written languages" (as opposed to "random or sematographic (heraldic) characters"). The Exeter analysts' claim has been criticized by linguists Mark Liberman and Richard Sproat on the grounds that the non-uniform distribution of symbols – taken to be evidence of writing – is little different from non-linguistic non-uniform distributions (such as die rolls), and that the Exeter team are using a definition of writing broader than that used by linguists. To date, even those who propose that the symbols should be considered "writing" from this mathematical approach do not have a suggested decipherment. Although earlier studies based on a contextual approach, postulating the identification of the pagan “pre-Christian Celtic Cult of the Archer Guardian”, have suggested possible clausal meanings for symbol pairs. Gallery of symbols A selection of the Pictish symbols, showing the variation between individual examples. Each group is classified as a single type by most researchers. Only the geometric and object types are represented here, not the animal group. Distribution and sites Only a few stones still stand at their original sites; most have been moved to museums or other protected sites. Some of the more notable individual examples and collections are listed below (Note that listing is no guarantee of unrestricted access, since
