The mediæval Roman nobles were most of them great farmers as well as fighters. Then, as now, land was the ultimate form of property, and its produce the usual form of wealth; and then, as now, many families were 'land-poor,' in the sense of owning tracts of country which yielded little or no income but represented considerable power, and furnished the owners with most of the necessaries of life, such rents as were collected being usually paid in kind, in oil and wine, in grain, fruit and vegetables, and even in salt meat, and horses, cattle for slaughtering and beasts of burden, not to speak of wool, hemp and flax, as well as firewood. But money was scarce and, consequently, all the things which only money could buy, so that a gown was a possession, and a corselet or a good sword a treasure. The small farmer of our times knows what it means to have plenty to eat and little to wear. His position is not essentially different from that of the average landed gentry in the Middle Age, not only in Italy, but all over Europe. In times when superiority lay in physical strength, courage, horsemanship and skill in the use of arms, the so-called gentleman was not distinguished from the plebeian by the newness or neatness of his clothes so much as by the nature and quality of the weapons he wore when he went abroad in peace or war, and very generally by being mounted on a good horse. In his home he was simple, even primitive. He desired space more than comfort, and comfort more than luxury. His furniture consisted almost entirely of beds, chests and benches, with few tables except such as were needed for eating. Beds were supported by boards laid on trestles, raised very high above the floor to be beyond the reach of rats, mice and other creatures. The lower mattress was filled with the dried leaves of the maize, and the upper one contained wool, with which the pillows also were stuffed. The floors of dwelling rooms were generally either paved with bricks or made of a sort of cement, composed of lime, sand and crushed brick, the whole being beaten down with iron pounders, while in the moist state, during three days. There were no carpets, and fresh rushes were strewn everywhere on the floors, which in summer were first watered, like a garden path, to lay the dust. There was no glass in the windows of ordinary rooms, and the consequence was that during the daytime people lived almost in the open air, in winter as well as summer; sunshine was a necessity of existence, and sheltered courts and cloistered walks were built like reservoirs for the light and heat.
