Among Celts in close contact with Ancient Rome, such as the Gauls and Celtiberians, their mythology did not survive the Roman empire, their subsequent conversion to Christianity, and the loss of their Celtic languages. It is mostly through contemporary Roman and Christian sources that their mythology has been preserved. The Celts peoples who maintained either their political or linguistic identities (such as the Gaels and Brythonic tribes of Great Britain and Ireland) left vestigial remnants of their forebears' mythologies, put into written form during the Middle Ages. Though the Celtic world at its apex covered much of western and central Europe, it was not politically unified nor was there any substantial central source of cultural influence or homogeneity; as a result, there was a great deal of variation in local practices of Celtic religion (although certain motifs, for example the god Lugh, appear to have diffused throughout the Celtic world)
cross to produce a short-legged bobtail. In theory, any of the bobtailed or tailless breeds could be used to produce bobtailed/tailless Munchkins. Not to be confused with the PixieBob is the Poly-Bob (1998) which is linked to the infamous Twisty Cats (cats bred for detrimental deformities). Poly-Bobs are not a recognised breed. They are bobtailed polydactyls which carry the harmful form of polydactyly which also causes gross deformities of the foreleg and front paws, including vestigial, absent or deformed leg bones and flipper-like forelimbs. No attempt has yet been made to eliminate these harmful effects and they represent the darker side of cat breeding (See Polydactyl Cats). Occasional tailless cats suggest a Manx-type mutation in which case the breeding line contains semi-lethal genes as well as genes for gross deformity. The current trend to developing hybrid domestic breeds by crossing domestic cats to wild
