It is generally admitted that place-names are more or less impervious to time and conquests. Instances seemingly without limit might be adduced of towns which have been sacked, destroyed, rebuilt, and rechristened, yet the original names--_and these only_--have survived. Dr. Taylor has observed that the names of five of the oldest cities of the world--Damascus, Hebron, Gaza, Sidon, and Hamath--are still pronounced in exactly the same manner as was the case thirty, or perhaps forty centuries ago, defying oftentimes the persistent attempts of rulers to substitute some other name.[39] As another instance of the permanency of place-names, the city of Palmyra is curiously notable. Though the Greek Palmyra is a title of 2000 years' standing, yet to the native Arab it is new-fangled, and he knows the place not as Palmyra but as Tadmor, its original and infinitely older name. Five hundred years B.C. the very ancient city of Mykenæ was destroyed and never rose again to any importance: Mykenæ was fabulously assigned to Perseus, and even to-day the stream which runs at the site is known as the Perseia.[40] If it be possible for local names thus to live handed down humbly from mouth to mouth for thousands of years, for aught one knows they may have endured for double or treble these periods; there is no seeming limit to their vitality, and they may be said to be as imperishable and as dateless as the stones of Avebury or Stonehenge. History knows nothing of violent and spasmodic jumps; the ideas of one era are impalpably transmitted to the next, and the continuity of custom makes it difficult to believe that the builders of Cyclopean works such as Avebury and Stonehenge, have left no imprint on our place-names, and no memories in our language. Even to-day the superstitious veneration for cromlechs and holy stones is not defunct, and it is largely due to that ingrained sentiment that more of these prehistoric monuments have not been converted into horse-troughs and pigsties. If, as now generally admitted, there has been an unbroken and continuous village-occupation, and if, as is also now granted, our sacred places mostly occupy aboriginal and time-honoured sites, it is difficult to conceive that place-names do not preserve some traces of their prehistoric meanings. In the case of villages dedicated to some saintly man or sweetest of sweet ladies, the connection is almost certainly intact; indeed, in instances the pagan barrows in the churchyard are often actually dedicated to some saint.[41]
