But the whole of this social life was fenced about by a written law. No title was valid for which a written document could not be produced, drawn up and attested in legal forms. The extensive commercial transactions of the Babylonians made this necessary, and the commercial spirit dominated Babylonian society. The scribe and the lawyer were needed at almost every juncture of life. The invention of the will or documentary testament, followed naturally. The same legal powers that were required to protect a man’s property during his lifetime were even more urgently required when he was dead. The will was at first the title which gave the heir his father’s estate. Gradually it developed, until at last it came to be an instrument by means of which the testator retained control over his property even after his death. As an example of the form which it usually assumed, we may take one which was drawn up in the seventh year of the reign of Cyrus as King of Babylon (532 B.C.): Nebo-baladan, the son of Samas-palassar, the son of the priest of the Sun-god, has, of his own free-will, sealed all his estate, which he had inherited from Nebo-balasu-iqbi, the son of Nur-Ea, the son of the priest of the Sun-god, the father of his mother, and from Kabtâ, the mother of Assat-Belit, his grandmother, consisting of a piece of land, a house and the slaves or serfs attached to it, in accordance with the will (_literally_ tablet) which his maternal grandfather, Nebo-balasu-iqbi, and his maternal grandmother, Kabtâ, had sealed and bequeathed to Nebo-baladan, the son of their daughter, and has bequeathed them for ever to Samas-palassar, the son of Samas-ina-esi-edher, the son of the priest of the Sun-god. As long as Nebo-baladan lives the piece of ground, the house, the slaves, and all the rest of his property shall continue in his own possession, according to the terms of this his will. Whoever shall attempt to change them, may Anu, Bel, and Ae curse him; may Nebo, the divine scribe of Ê-Saggil, cut off his days! This will has been sealed in the presence of Sula, son of Bania, son of Epes-ilu; of Bel-iddin, son of Bel-natsir, son of the priest of Gula; of Nebo-sum-yukin, son of Sula, son of Sigua; of Nebo-natsir, son of Ziria, son of Sumâti; … of Nebo-sum-lisir, son of Nebo-sum-iskun, son of the wine-merchant (?), and the scribe Samas-zir-yusabsi, son of Zariqu-iddin, son of the architect. (Written at) Babylon, the 19th day of Sebat (February), the seventh year of Cyrus, king of Babylon and the world. In this case it is a son who makes over his property to his father should he be the first to die. The will shows that the son was absolute master of his own possessions even during his father’s lifetime, and could bequeath it as he chose.
