This excellent coloured map, covering all of Britain north of latitude 52 DG including the Orkney Islands and much of Ireland, completes the British contribution to the Tabula Imperii Romani , the International Map of the Roman Empire. It shows many sites that have not yet been fully investigated, and has a full index with a complete list of references. The decision to produce maps covering the whole of the Roman Empire at a uniform scale of 1/1,000,000 was made at a meeting of the International Geographical Union in 1928. Each sheet covers an area of 4 DG latitude by 6 DG longitude. The maps not only place all known towns, temples, villas, etc. cartographically, but most of their indexes also supply a detailed bibliography of each feature. Roman historians and archaeologists.
