This was the case with London. The trading season was in July and August, as I read the story: during these months the high ground either on the east or the west of Walbrook was covered with shops and booths made of wattle and clay. When the Fair was over the temporary structures were taken down, or perhaps left to be repaired in the following season; the conflux of people vanished, and there was no Port of London for another year. London had no importance at all except during the short season of the Fair. Nor were there any residents of importance. There were left none others than the humble folk who fished in the river, trapped the birds of the marsh, hunted in the forests, and worked for the ships while they were in the Port.

I think that the annual Fair was held on the west side of Walbrook, for the simple reason that the Romans, when they built their citadel, chose the eastern side—that is to say, they took the eastern hill because they were unwilling to interfere with the trade of the place, which was mainly carried on upon the western hill. There was no bridge as yet—otherwise there could have been no massacre by the offended Queen (see p. [59]). As to the time when trade became large, and so continuous as to demand the erection of warehouses and the creation of a body of wholesale merchants, I am not able to offer even an approximate opinion. My conclusions belong to an earlier time, yet partly a Roman time, when London represented nothing but an annual Fair, while there were no public buildings, no municipal institutions, no officers or rulers, except the temporary administrators of a temporary exhibition. And, as at a Fair, when it was over nothing was left in store or warehouse for the next year. The ships left their imports behind them, and brought back exports with them.

It would be interesting to inquire into the continuance of the summer trade and the slackness of the winter long after the character of the annual Fair had left London. Galleys came, we know, from Venice and Genoa every summer; ships laden with wine came every summer from Bordeaux; ships of the Hanseatic League put out and came into port every summer from north Europe and the Baltic. What was done in the twelfth century, for example, during the winter? What amount of trade could have been carried over roads which for two-thirds of the year were practically impassable?

The theory of the Fair explains why Cæsar made no mention of London, and why the Romans at first placed no permanent garrison in the place: they saw it crowded for a few weeks, and then deserted and of no account. The massacre of Boadicea first awakened them to a sense of its strategic as well as its commercial importance. When they built their citadel and their bridge it was not only to defend the trade of a few weeks and the scanty population of fisher-folk, but also to seize and to occupy a stronghold of capital importance as a great military as well as a great commercial centre. It also explains why no remains of pre-Roman buildings have been found on the site of London. Because there were none. The copia mercatorum came, stayed a few weeks or days, and went away. They found inns and booths for their accommodation; when they left, the inns and booths were closed, or left to fall to pieces, for another twelve months.

In the course of time, when the bulk of trade increased and goods of all kinds began to be stored in warehouses and kept over from year to year, the limits of the busy time were naturally extended. There was a great deal to be done in the way of warehousing, arrangement for the next summer, arrangement with retail merchants and the owners of caravans which went about the country. But there still remained the time—six or eight months—during which no ships arrived in port, and the roads of the country were impassable.

The warehousing, with the rise of a class of men who held the warehouses and became wholesale merchants, marks a period of extension and increase in the trade of the Port.

PAVEMENT BEFORE THE ALTAR OF THE PRIOR’S CHAPEL AT ELY
From Archæologia, vol. x.

With the Romans came the time of good roads, warehouses, a settled and continuous trade, a class of wholesale merchants, quays of convenient size, new and artificial ports, and the residence for life of a wealthy and highly civilised community who built villas along the banks of the Walbrook, and imitated, though imperfectly, the arts and civilisation of Bordeaux, Marseilles, Treves, and even of Rome.

One point more may be noticed before we step into the open light of history. The position of London from the very first has been that of a town which has had to depend upon outside or distant places for her supplies. In front of her, on either side of her stretched marshes; behind her stretched moorland: she could grow nothing for her own people. Outside other towns lay farms, gardens, and pastures: outside London there was neither farm, nor garden, nor pasture; except the fish in the river and the fowl in the marsh-land, there was nothing. The merchant in the time of Agricola, as much as the merchant in the time of Victoria, lived upon food brought in by private enterprise.
