There is not even a trace to be found in these codes of law of an earlier system of non-division. When they lay down that land is hereditary, or that it can be sold, they do not say that this was a novelty. It is easy for Maurer to declare that these practices were borrowed from Roman law; this is a convenient hypothesis, but one for which there is no proof. The fact is that the earlier condition of things, of which we can see the traces in German legislation, was not communism, but the common ownership of the _family_. We find signs of this in the Salic and in the Ripuarian law, and in the codes of the Burgundians and Thuringians. The revolution in the land system which took place at this period was a change not from common ownership to private ownership, but from the ownership of the family to that of the individual. The practices of bequest and of sale are the chief marks of this great change; and it is this alone that we can attribute to the influence of Roman law: while even here it seems to me that it would be safer to regard it rather as a natural process of evolution which has taken place in every nation. If in German law Maurer can discover no trace of the mark or of community in land, what are the documents on which he rests his proof of their existence? If we study his book with some attention, we shall be surprised to find that he goes for his authorities to the _Traditiones_, under which title are classed the various collections of charters of the 8th to the 14th centuries.[101] But all these, and they number almost ten thousand, are, without exception, deeds of private property. In fact, they are always either deeds of gift, or of sale, or of exchange, or of the grant of _precaria_. It is impossible not to allow that the thousands of deeds of this kind are so many proofs of private property, since you can neither sell nor give away what is not already your own. Amongst these collections we also find judicial decisions, and they all point in the same direction.
