[363] The joinder of times to make out a title was soon allowed between buyer and seller, and I have no doubt, from the language always used by the Roman lawyers, that it was arrived at in the way I have suggested. A passage from Scaevola (B. C. 30) will furnish sufficient proof. Joinder of possessions, he says, that is, the right to add the time of one's predecessor's holding to one's own, clearly belongs to those who succeed to the place of others, whether by contract or by will: for heirs and those who are treated as holding the place of successors are allowed to add their testator's possession to their own. Accordingly, if you sell me a slave I shall have the benefit of your holding. /1/ The joinder of times is given to those who succeed to the place of another. Ulpian cites a like phrase from a jurisconsult of the time of the Antonines,--"to whose place I have succeeded by inheritance, or purchase, or any other right." /2/ Succedere in locum aliorum, like sustinere personam, is an expression of the Roman lawyers for those continuations of one man's legal position by another of which the type was the succession of heir to ancestor. Suecedere alone is used in the sense of inherit, /3/ and successio in that of "inheritance." /4/ The succession par excellence was the inheritance; and it is believed that scarcely any instance will be found in the Roman sources where "succession" does not convey that analogy, and indicate the partial [364] assumption, at least, of a persona formerly sustained by another. It clearly does so in the passage before us. But the succession which admits a joinder of times is not hereditary succession alone. In the passage which has been cited Scaevola says that it may be by contract or purchase, as well as by inheritance or will. It may be singular, as well as universal. The jurists often mention antithetically universal successions and those confined to a single specific thing. Ulpian says that a man succeeds to another's place, whether his succession be universal or to the single object. /1/ If further evidence were wanting for the present argument, it would be found in another expression of Ulpian's. He speaks of the benefit of joinder as derived from the persona of the grantor. "He to whom a thing is granted shall have the benefit of joinder from the persona of his grantor." /2/ A benefit cannot be derived from a persona except by sustaining it. It farther appears pretty plainly from Justinian's Institutes and the Digest, that the benefit was not extended to purchasers in all cases until a pretty late period. /3/
