3. The comparison of Roman Treves with the later Roman London is most curious, and brings out very unexpectedly the fact that in many respects the latter was an enlargement of the citadel. We know that the wall was constructed hastily, and that all the stonework in the City was used in making it. Like the citadel, however, and like Treves, it had a stream on one side, baths and a bridge and a port within the walls; while the official buildings, as at Treves, were all collected together in one spot. We also find the curious angle, which at Treves may be accounted for by an enlargement of the wall, and at London by the custom of keeping the amphitheatre outside the City as a place foul with associations of battle, murder, massacre, and the ribald company of gladiators, retiarii, prisoners waiting the time of combat and of death, wild beasts and their keepers, and the rabble rout which belonged to this savage and reckless company.
That part of London lying to the west of Walbrook was crowded with the houses of the lower classes, and with the warehouses and stores of the merchants. These extended, as they do to this day, all the way from the Tower to Blackfriars. On the rising ground above were the villas of the better class, some of them luxurious, ample, decorated with the highest art, and provided with large gardens. These villas extended northwards along the banks of the little Walbrook. They are also found on the south side in Southwark, and on the west side on Holborn Hill. The principal street of Augusta was that afterwards called Watling Street, which, diverted from the old Watling Street where Marble Arch now stands, carried all the trade of the country through London by way of Newgate, over the present site of St. Paul’s, and so through the citadel, to the market-place and to the port. Another street led out by way of Bishopsgate to the north; and a third, the Vicinal Way, to the eastern counties. The bridge led to a road running south to Dover. There was also a long street, with probably many side streets out of it, as there are at this day, along the Thames.
The things which remain of Roman London and may be seen in our museums are meagre, but they yield a good deal of information as to the condition and the civilisation of the City. The foundation of large villas, the rich mosaics and pavements, the remains of statues, the capitals of pillars, the coins, and the foundations of massive walls, clearly indicate the existence of much wealth and considerable comfort. The smaller things in the glass cases, the keys, the hairpins, the glass bottles, the statuettes, the bells, the tools, the steelyards, the mirrors, all point to a civilisation closely imitating that of the capital itself.
