Druids or no Druids there must at some period in our past have been interesting and enterprising people in these islands. At Avebury, near Marlborough, is Silbury Hill, an earth mound, which is admittedly the vastest artificial hill in Europe. Avebury itself is said to constitute the greatest megalithic monument in Europe, and nowhere in the world are tumuli more plentiful than in Great Britain. On the banks of the Boyne is a pyramid of stones which, had it been situated on the banks of the Nile, would probably have been pronounced the oldest and most venerable of the pyramids. In the Orkneys at Hoy is almost the counterpart to an Egyptian marvel which, according to Herodotus, was an edifice 21 cubits in length, 14 in breadth, and 8 in height, the whole consisting only of one single stone, brought thither by sea from a place about 20 days' sailing from Sais. The Hoy relic is an obelisk 36 feet long by 18 feet broad, by 9 feet deep. "No other stones are near it. 'Tis all hollowed within or scooped by human art and industry, having a door at the east end 2 feet square with a stone of the same dimension lying about 2 feet from it, which was intended no doubt to close the entrance. Within, there is at the south end of it, cut out, the form of a bed and pillow capable to hold two persons."[11] Sir John Morris-Jones has noted remarkable identities between the syntax of Welsh and that of early Egyptian: Gerald Massey, in his _Book of the Beginnings_, gives a list of 3000 close similarities between English and Egyptian words; and the astronomical inquiries of Sir Norman Lockyer have driven him to conclude: "The people who honoured us with their presence here in Britain some 4000 years ago, had evidently, some way or other, had communicated to them a very complete Egyptian culture, and they determined their time of night just in the same way that the Egyptians did". It used to be customary to attribute all the mysterious edifices of these islands, including stones inscribed with lettering in an unknown script, to hypothetical wanderers from the East. Nothing could have been more peremptory than the manner in which this theory was enunciated by its supporters, among whom were included all or nearly all the great names of the period. To-day there is a complete _volte face_ upon this subject, and the latest opinion is that "not a particle of evidence has been adduced in favour of any migration from the East".[12] When one remembers that only a year or two ago practically the whole of the academic world gave an exuberant and unqualified adherence to the theory of Asiatic immigration it is difficult to conceive a more chastening commentary upon the value of _ex cathedra_ teaching.
