The small class of well-to-do commoners, the merchants and goldsmiths, such as they were, who stood between the nobles and the poor people, imitated the nobles as much as they could, and strengthened their houses by every means. For their dwellings were their warehouses, and in times of disturbance the first instinct of the people was to rob the merchants, unless they chanced to be strong enough to rob the nobles, as sometimes happened. But in Rome the merchants were few, and were very generally retainers or dependants of the great houses. It is frequent in the chronicles to find a man mentioned as the 'merchant' of the Colonna family, or of the Orsini, or of one of the independent Italian princes, like the Duke of Urbino. Such a man acted as agent to sell the produce of a great estate; part of his business was to lend money to the owner, and he also imported from abroad the scanty merchandise which could be imported at all. About half of it usually fell into the hands of highwaymen before it reached the city, and the price of luxuries was proportionately high. Such men, of course, lived well, though there was a wide difference between their mode of life and that of the nobles, not so much in matters of abundance and luxury, as in principle. The chief rule was that the wives and daughters of the middle class did a certain amount of housekeeping work, whereas the wives and daughters of the nobles did not. The burgher's wife kept house herself, overlooked the cooking, and sometimes cooked a choice dish with her own hands, and taught her daughters to do so. A merchant might have a considerable retinue of men, for his service and protection, and they carried staves when they accompanied their master abroad, and lanterns at night. But the baron's men were men-at-arms,--practically soldiers,--who wore his colours, and carried swords and pikes, and lit the way for their lord at night with torches, always the privilege of the nobles. As a matter of fact, they were generally the most dangerous cutthroats whom the nobleman was able to engage, highwaymen, brigands and outlaws, whom he protected against the semblance of the law; whereas the merchant's train consisted of honest men who worked for him in his warehouse, or they were countrymen from his farms, if he had any. It is not easy to give any adequate idea of those great mediæval establishments, except by their analogy with the later ones that came after them. They were enormous in extent, and singularly uncomfortable in their internal arrangement.
