London, in Cæsar's time, was most probably a City of Ships; that is to say it traded with Gaul, and had a number of boats on its marshy river. Cæsar's pretence for invading England, was, that it was too good a provider for Gaul, and rendered his conquest of that country difficult. But it is doubtful whether he ever beheld or even alludes to the infant metropolis. His countrymen are supposed to have first taken possession of it about a hundred years afterwards, in the reign of Claudius. They had heard of a pearl-fishery, says Gibbon. At all events they found oysters; for Sandwich (Rutupium) became famous with them for that luxury.
It is not our design, in this Introduction, to give anything more than a sketch of the rise and growth of the metropolis; we shall leave the rest to be gathered as we proceed. Our intention is to go through London, quarter by quarter, and to notice the memorials as they arise; a plan, which, compared with others (at least if we are to judge of the effect which it has had on ourselves), seems to possess something of the superiority of sight over hearsay. When we read of events in their ordinary train, we pitch ourselves with difficulty into the scenes of action--sometimes wholly omit to do so; and there is a want of life and presence in them accordingly. When we are placed in the scenes themselves, and told to look about us--such and such a thing having happened in _that_ house--_this_ street being one in which another famous adventure took place, and _that_ old mansion having been the dwelling of wit or beauty, we find ourselves comparatively at home, and enjoy the probability and the spectacle twice as much. We feel (especially if we are personally conversant with the spot) as if Shakspeare and Milton, Pope, Gay, and Arbuthnot, the club at the Mermaid, and the beauties at the court of White-Hall, were our next-door neighbours.
We shall take the reader, then, as speedily as possible among the quarters alluded to, and trouble him very little beforehand with dry abstracts and chronologies, or with races of men almost as uninteresting. The most patriotic reader of our history feels that he cares very little for his ancestors the Britons; of whom almost all he knows is, that they painted their skins, and made war in chariots. Nor do the Romans in England interest us more. They are men in helmets and short skirts, who have left us no memorial but a road or two, and an iron name. That is all that we know of them, and we care accordingly. Perhaps the Saxons, after having destroyed the Roman architecture as much as possible, and repented of it, took their own from what had survived. The greatest relic of Cæsar's countrymen in the metropolis was the piece of wall which ran lately south of Moorfields, in a street still designated as London Wall. The Romans had a vast material genius, not so intellectual as that of the Greeks, nor so calculated to move the world ultimately, but highly fitted to prepare the way for better impressions, by showing what the hand could perform; and as they built their wall in their usual giant style of solidity, it remained a long while to testify their magnificence. Small relics of it are yet to be seen in Little Bridge Street, behind Ludgate Hill; on the north of Bull-and-Mouth Street, between that street and St. Botolph's Churchyard; and on the south side of the Churchyard of Cripplegate. There was another in the garden of Stationer's Hall, but it has been blocked up.
