Damnonii, and Selgovae between the Tyne and the Forth. Finally,
the Midlands, parcelled up by the forests of Sherwood, Needwood,
Charnwood, and Arden, into quarters, found space for the Dobuni in the
Severn valley (to the west of the Cateuchlani), for the Coritani east
of the Trent, and for their westward neighbours the Cornavii.[48]

G. 6.--All these tribes are given in Ptolemy's geography, but only a
few, such as the Iceni, the Silurians, and the Brigantes, meet us
in actual history; whilst, of them all, the Damnonian name alone
reappears after the fall of the Roman dominion. Thus the accepted
allotment of tribal territory is largely conjectural. North of the
Forth all is conjecture pure and simple, so far as the location of
the various Caledonian sub-clans is concerned. We only know that there
were about a dozen of them; the Cornavii, Carini, Carnonacae,
Cerones, Decantae, Epidii, Horestae, Lugi, Novantae, Smertae, Taexali,
Vacomagi, and Vernicomes. Some of these may be alternative names.

G. 7.--The practical importance of the above-mentioned natural
divisions of the island is testified to by the abiding character of
the corresponding political divisions. The resemblance which at once
strikes the eye between the map of Roman and Saxon Britain is no mere
coincidence. Physical considerations brought about the boundaries
between the Roman "provinces" and the Anglo-Saxon principalities
alike. Thus a glance will show that Britannia Prima, Britannia
Secunda, Maxima Caesariensis, and Flavia Caesariensis correspond to
the later Wessex, Wales, Northumbria, and Mercia (with its dependency
East Anglia).[49] And even the sub-divisions remained approximately
the same. In Anglo-Saxon times, for example, the Midlands were still
divided into the same four tribal territories; the North Mercians
holding that of the British Cornavii, the South Mercians that of the
