168 THE DEVELOPMENT OF ARCHITECTURE IN ESSEX. its competitor was a Christian church, and buildings of this class especially were treated as quarries from which to obtain building material, and I am afraid what was still worse, as it meant absolute destruction, they were used as quarries for road material. If, in your perambulations you will note the materials of which our old parish churches were erected you will find in very numerous instances Roman bricks and Septaria mixed with other material, this indicates that near by once stood a building of the Roman period. I have long had a strong conviction that the site of many of our old moated manor houses, especially those which are within a short distance of one of the old Roman roads, were, in the Roman period, military stations, and if so, in addition to the defensive earth- works and water moat by which they were surrounded, there would be a substantial residence for the Commandant, the materials of which were re-used when the Norman lord required materials for his church or his new buildings. I have often been surprised when conning over the plans of Roman villas, which have been discovered in this county and elsewhere, of the comparative thinness of the walls as compared with those which were considered necessary by the Normans. The Roman walls of houses seldom exceed 2ft, in thick- ness, whilst a Norman would not consider himself secure with walls of a less thickness than from 4ft. to 5 ft. From fragments left to us, the Roman villas would seem to have had rich pavements and the interior walls plastered and decorated in divers colours. All these things seem to indicate that the Roman occupiers, after having thoroughly cowed the ancient inhabitants, lived here for two or three centuries in comparative luxury and safety. As the Roman power became weakened, the old British races became emboldened, until upon the final withdrawal of the Roman troops they reasserted their power and, as usual with undisciplined and barbarous troops, gave way to the wildest excesses and destroyed with fire the belong- ings of their late masters, and certainly traces of fire have been found in many of these Roman remains when unearthed, which seems to support this suggestion. After the departure of the Romans the country was rent and devastated by the British princes who had assumed the sovereignty, and the invaders, who were attracted by the spoil—the Jutes, the Saxons, and the Angles—until at last the Saxons gradually established themselves in the country, Essex, with Middlesex and part of Herts, falling to the East Saxons, whose kings continued to reign from
