If a man was sued for property which he had bought from another, the regular course of litigation was for the defendant to summon in his seller to take charge of the defence, and for him, in turn, to summon in his, if he had one, and so on until a party was reached in the chain of title who finally took the burden of the case upon himself. A contrast which was early stated between the Lombard and the Roman law existed equally between the Anglo-Saxon and the Roman. It was said that the Lombard presents his grantor, the Roman stands in his grantor's shoes,--Langobardus dat auctorem, Romanus stat loco auctoris. /1/ Suppose, now, that A gave land to B, and B conveyed over to C. If C was sued by D, claiming a better title, C practically got the benefit of A's warranty, /2/ because, when he summoned B, B would summon A, and thus A [373] would defend the case in the end. But it might happen that between the time when B conveyed to C, and the time when the action was begun, B had died. If he left an heir, C might still be protected. But supposing B left no heir, C got no help from A, who in the other event would have defended his suit. This no doubt was the law in the Anglo-Saxon period, but it was manifestly unsatisfactory. We may conjecture, with a good deal of confidence, that a remedy would be found as soon as there was machinery to make it possible. This was furnished by the Roman law. According to that system, the buyer stood in the place of his seller, and a fusion of the Roman with the Anglo-Saxon rule was all that was needed. Bracton, who modelled his book upon the writings of the mediaeval civilians, shows how this thought was used. He first puts the case of a conveyance with the usual clause binding the grantor and his heirs to warrant and defend the grantee and his heirs. He then goes on: "Again one may make his gift greater and make other persons quasi heirs [of his grantee], although, in fact, they are not heirs, as when he says in the gift, to have and to hold to such a one and his heirs, or to whomsoever he shall choose to give or assign the said land, and I and my heirs will warrant to the said so and so, and his heirs, or to whomsoever he shall choose to give or assign the said land, and their heirs, against all persons. In which case if the grantee shall have given or assigned the land, and then have died without heirs, the [first] grantor and his heirs begin to hold the place of the first grantee and his heirs, and are in place of the first grantee's heir (pro herede) so far as concerns warranting to his assigns and their heirs [374] according to the clause contained in the first grantor's charter, which would not be but for the mention of assigns in the first gift. But so long as the first grantee survives, or his heirs, they are held to warranty, and not the first grantor." /1/
