I must take notice of another use in our map. In the province of _Brittania Prima_ are two _Venta_’s; but till now we could not ascertain them both: the map shows us, one is _Wimborn minster_, the other _Winchester_: the former is on the river _Alauna_, seen plainly in _Blandford_, being the ford over the _Alauna_; _Llaunford_, in the Belgic pronunciation: called now _Allen_ river. Our author calls _Canterbury_, _Cantiopolis_, though before we knew no other name it had than _Durovernum_: but the modern name of _Canterbury_ seems derived from the former; and the termination favours our author’s observation, in another part of his history, of remains of Greek traders preserved in some places; of which several more instances may be given. I extend my inquiries here, on Richard of Cirencester’s map, no further than our island of Britain; leaving that of Ireland to those that have proper opportunities. Nor shall I pretend to assign places in Scotland, any further than the map directs me; but leave them too to those that have proper opportunities of inquiry, in that kingdom. III. Let us now proceed to his Itinerary; a truly invaluable monument! From these two we may hope to obtain a complete knowledge of Roman Britain. CAPUT VII. Our author calls these, _Iters_ of his _Diaphragmata_, from their similitude to the animal midriff, passing through the body from side to side. _Rhutupis colonia_, Sandwich, Richborough and Stonar castle, Kent, is the first city, says our author, in the island of Britain, towards Gaul; situate among the _Cantii_, opposite to _Gessoriagum_, the port of _Bononia_, Boloign. Hence is the most commodious passage of +CCCCL.+ _stadia_, or, as others will have it, +XLVI.+ miles. From that city _Rhutupium_, says he, is drawn the Roman way called Guithlin-street, quite to _Segontium_, Caernarvon, through the space of +CCCXXIV.+ miles, or thereabouts. Thus, To _Cantiopolis_, which is also called _Durobernum_, _stipendiaria_, Canterbury, Kent, +X.+ miles. _Durosevum_ +XII.+ Sittingburn, Kent. XXV. _Duroprovis_, _stipendiaria_, Rochester, Kent. Thence, at +XXVII.+ miles, it passes the Thames, and enters the province _Flavia_, and the city of _Londinium Augusta_, London. Thence IX. To _Sulloniagis_, _Suellaniacis_, Edgeware, Middlesex. XII. _Verolamium_, _municipium_, Verlamcester, or St. Alban’s. Of this place were Amphibalus and Albanus, martyrs. XII. _Forum Dianæ_, Market street, near Dunstable, Hertfordshire. XII. _Magiovinium_, Dunstable, Bedfordshire. XII. _Lactorodum_, Stoney Stratford, Bucks. XII. _Isannavaria_, _Isantavaria_, Towcester, Northamptonshire. XII.
