4 ANCIENT EARTHWORKS IN EPPING FOREST. Those portions of Ambresbury Bank which are almost perfect, exhibit a deep and broad moat, with a strong inner embankment, and a slighter external one. Two of the angles point very nearly north and south. The plan is not a regular square, but an irregular quadrangle, the shorter sides being those between the north and east, the east and south, and the south and west; the remaining and longer side has an obvious outward curve. There are various entrances, and there have been, I think, two at least on every side. The southern angle is least perfect, and was probably never closed, and all the other angles are slightly rounded. At what we may term the southern angle (towards the west), the work is so arranged as to inclose part of a low-lying strip of ground adjacent to a water-course, the intention probably being to ensure a water-supply on the inside, and a ditch on the outside. The whole of the inte- terior, and part of the exterior is more or less wooded,— densely so on the south-west and south, where an ordinary visitor will be very likely to overlook the bank, which is carried through the swamp. The entire area comprises about twelve acres, according to Mr. D'Oyley, who has been good enough to survey it, and it is as nearly as possible of the same extent as the camp at Loughton. It is to be regretted that very recently as well as formerly, the Ambresbury Camp has been greatly disfigured by Essex Vandals, and in some parts almost obliterated by seekers for sand and other materials. The timber also has suffered considerably. But still we have a well-defined and strongly defended entrenchment. Outside the enclosure on the east the surface is irregular, but I have not explored it enough to say more than that the irregularity seems not wholly due to common gravel and sand diggers, whose doings are for the most part easily identified. We may now refer to the common local name of this camp, which is Ambresbury or Amesbury, and is exactly identical with that of a well-known town in Wiltshire, with its neighbouring Stonehenge and Vespasian's Camp. They say that Ambresbury is named after Ambrosius Aurelius, a celebrated opposer of the Saxons. If this is right, the Epping Camp is associated with the most romantic period of our history, and may conjure up visions of Vortigern and Arthur, and Merlin, and a host of other legendary heroes.
