CENTURIATION IN ESSEX. 211 like network of paths or roads dividing the arable land into a number of plots or possessae a little larger than one square mile in extent. The possessae suffered further division into still smaller square plots of land having a side a little shorter than a quarter mile and known as centuries. Changes usually occurred in the direction of the bounding paths when some physical feature, such as a range of hills or a river, made a different orientation necessary. In a centuriated area the cultivated plots would have appeared from above rather like the modern American farmsteads of the Middle West with their typical rectangular plan. Examples of Roman centuriation are still visible at a number of places in Italy, notably Musa, and again farther north as at Orange in Westphalia. The late Professor Haverfield, whilst casting some doubt on a suggested centuriation plan for Middlesex9, carried out some work in connection with vestiges of centuriation in Essex. He demonstrated that on the present day road map there was some evidence of parallelism to be observed in certain Essex roads. He furthermore indicated that the parallelism seemed unnecessary unless serving some purpose other than that of communication. Finally he allowed the possibility of these roads being part of some land division of Roman times, but suggested that there seemed little other evidence in the routeways to indicate the onetime existence of centuriation in Essex. The results of an attempt to trace further vestiges of Roman centuriation in Essex appear in Plate VIII. Working with large scale maps, every existing road, lane, and footpath which may be regarded as forming part of an ancient rectangular network was noted and placed on the small scale map. Many of the roads appearing here were checked by practical fieldwork. Modern roads, with their tendency to follow the grid-like course of their predecessors, have been excluded. While this map is not claimed as definite proof of Roman Centuriation, it displays features that can only with difficulty be otherwise explained. It is immediately apparent that the pattern falls into three areas of differing orientation divided by some kind of physical feature. The entire north-west of Essex and the Tendring area form one tract in which the scattered lineaments show parallelism. 9 Middlesex in British, Roman and Saxon Times, Montague Sharpe.
