We may safely conclude that the massacre of London by the troops of Boadicea would not have occurred had there been a bridge by which the people could escape. It is also safe to conclude that the construction of a bridge was resolved upon and carried out at the same time as that of the fortress. In another place will be found my theory as to the kind of bridge first constructed by the Roman engineers. In this place we need only call attention to the fact of the construction and to the gate which connected the fort with the bridge.

After the campaigns of Agricola, history speaks but little of Britain for more than half a century; though we hear of the spread of learning and eloquence in the north and west:—

Nunc totus Graias nostrasque habet orbis Athenas;

Gallia causidicos facunda Britannos;

De conducendo loquitur jam rhetore Thule.

And Martial says, with pride, that even the Britons read his verses:—

Dicitur et nostros cantare Britannia versus.

These, however, may be taken as poetic exaggerations.

The Romans, it is quite certain, were consolidating their power by building towns, making roads, spreading their circle of influence, and disarming the people. It has been remarked that the tessellated pavements found in such numbers frequently represent the legend of Orpheus taming the creatures—Orpheus was Rome; the creatures were her subjects.

The first half-century of occupation was by no means an unchequered period of success: the savage tribes of the north, the Caledonii, were constantly making raids and incursions into the country, rendered so much the easier by the new and excellent high roads.
