But though, on general grounds, a very remote antiquity may safely be attributed to both town and fortress, it is difficult to find any precise or special evidence on which to rest the claim. Here, as at Durovernum or Canterbury, the Roman form indicates a British origin, and, if the ancient name of the stream be indeed, as asserted, the Dour, may well be derived from it, and the Castle Hill is just the place upon which a British camp is likely to be found. The commerce of the Britons, known to have been carried on with activity through the Cornish ports and the Isle of Wight, has also been claimed for the route through Dover. The actual present traces of British occupation in this southern country are indeed very scanty, and confined to a few names of rivers and hills, a very few of towns or villages, and to occasional entrenchments upon high ground, and of an irregular outline. The great roads, whatever their remote origin, in their present form carry the stamp of Rome upon every mile of their course, and the oldest known works in masonry are due to the same people, while the general topography, all that relates to property and self-government, hundreds, lathes, rapes and tythings, parish and hamlet, grange and farm, and the crowd of bourns, dens, hams, hangers, hirsts, ings, tons, wolds and worths point with overwhelming force to the English settlers. Even the tenure in gavelkind, claimed as a British custom, and known in Wales by the expressive name of “Randyr” or “partible” land, is by most legal antiquaries regarded as Teutonic. Although Cæsar does not mention Dover by name, there can be no doubt that his fleet lay before it in August, B.C. 55, the period of his first invasion of Britain. Dr. Guest has clearly demonstrated that the Portus Icius whence he sailed was a small and now silted-up haven between Cape Gris Nez, the Ician promontory, and Wissant, whence a ten hours’ course brought him in the morning abreast of Dover. Here he found the natives, in great numbers and armed, drawn up to oppose his landing. He therefore anchored in Dover Wick, the roadstead east of the town, to give time for his slower ships to arrive, and thence proceeded to Deal, where he probably landed with two legions, or from eight to ten thousand men. Dr. Guest has pointed out that the word Icius coincides closely with the Irish name for the English Channel, “Muir n’Icht,” “the Ician Sea,” “icht” being a form of “uch” or “ucha,” upper in height, which plays so important a part in the names of places in Wales and the north of Scotland. It was natural that the Channel should be named from its most remarkable feature, and to this day its name in Dutch is “De Hofden,” or “the heights.”
