There can be little doubt that the unit of the Babylonian system was the light shekel (Daric or ox-unit) of 130-5 grs. Troy. But I have shown that the Chaldaeans were aware of and made use of the method of fixing weight-units by means of grains of corn such as we have found to be the universal practice from Ireland to China, and we have at once removed all need for supposing that it was only when they had discovered a scientific method of metrology that the Chaldaeans constructed their weight-unit.
After what we have shown upon p. 115 concerning the methods employed in the buying and selling of corn, where it has been made clear that of all commodities corn is one of the very last to be weighed because of its bulkiness in proportion to its cheapness, I think no one will readily accept M. Aurè’s ingenious hypothesis[314].
Are we not now justified in supposing that, just as the peoples of Mesopotamia had marked their seasons and time by primitive methods, and used their fingers and hands and feet as measures long before they dreamed of scientific methods, so that likewise they had employed for weighing their gold the natural weight-unit which lay ready to their hands in the wheat-ears that crowned their plains.
Let us now start with the light shekel as our unit. According to our argument it was nothing more than the amount of gold which represented the value of the cow, the unit of barter throughout all Europe, Asia and Africa, as it still is over considerable areas of both the latter continents. There is no reason for not believing that as among other people, all articles of property, utensils, weapons, clothes, ornaments and the various kinds of animals stand to one another in well-known relations of value, so the same principle was in full force among the Semites of Mesopotamia. We found that the wild tribes of Laos had a regular scale commencing with a hoe as their lowest unit, leading up through kettles and porcelain jars to the buffalo, their main unit; we also found that the weight of a grain of corn in gold was equated to a hoe, and that thus by a simple process of multiplication it was easy to ascertain the value of a buffalo in gold. The unit thus attained was kept from fluctuating, as it was known to every one how many grains of corn gave the true weight of the unit. The practical accuracy of this method of fixing monetary units has been demonstrated from the case of the Early English and Mediaeval English silver penny ([p. 180]). There is complete evidence to show that the light shekel system was older than the heavy system. Firstly the so-called Duck weights with their cuneiform inscriptions point to the fact that Babylonia was the special home of this system, whilst the Lion weights with their Aramaic inscriptions point to a later period, when the Assyrian Empire was in immediate touch with the merchants of Phoenicia. But, in the next place, a far more powerful argument can be drawn from the Hebrew system. In later times the heavy shekel system prevailed in Palestine, in accordance with which the maneh contained 50 heavy or double shekels of 200 grs. each. But that this maneh was simply imposed on the older light shekel system is demonstrated from the fact that when in two parallel passages articles of a certain weight of gold are mentioned, in the one the weight is given at three manehs, in the other at 300 shekels, the maneh thus being counted at 100 shekels. These 100 shekels are equal to the 50 heavy shekels of the heavy Assyrian or Aramaic maneh. Now it is evident that if the heavy system had been the original one employed by the Hebrews, the maneh would simply have been reckoned at 50 (heavy) shekels. As the matter stands it is evident that on the contrary, the heavy mina was introduced into a system where the unit was simply the light shekel, and the Hebrews therefore clinging to their old unit, described the maneh as consisting of 100 shekels instead of 50. Further evidence to the same effect will be adduced later on. Finding thus the light shekel in Babylonia, in Palestine and in Egypt, and current even under the Assyrian Empire side by side with the heavy system even amongst people who used the Aramaic system of writing, we may without any hesitation regard it as the older.
The process by which the gold Talent was arrived at was somewhat thus:
The ox-unit of 130-135 grs. is the basis.
Next the fivefold of this was taken, whether from five being the simplest multiple, since it was suggested from the primitive method of counting by the fingers of one hand, or far less likely from a slave being estimated at 5 oxen, somewhat as we find among the Homeric Greeks an ordinary slave-woman estimated at four cows, and in ancient Ireland at three cows. This weight is known as the Assyrian five-shekel standard, and from it Mr Petrie derives the 80-grain standard which he detects as the unit of a certain number of weights found at Naucratis (Naukratis, p. 86). Whilst the Egyptians contented themselves with the 5 ket and 10 ket, or uten, as their highest unit, the Chaldaeans advanced to the fifty-fold (5 × 10), and thus obtained that which probably for a long time formed their highest unit.
What was this Maneh? Is it a Semitic word or is it rather an Aryan, as the present writer has argued elsewhere[315]? At all events it is interesting to find the appearance of a similar word in the Rig Veda and that too in connection with gold: this has been regarded by some as a loan word from Babylon[316]. But it is equally possible, that it is a “loan word” from India to Babylon. The maneh evidently belongs to a period anterior to the development of the sexagesimal system, for if it had come into use along with or subsequent to that system, we should certainly find 60 instead of 50 shekels in the mina of gold and the mina of silver: hence it cannot in any wise be regarded as a distinctive feature of the Babylonian scientific system, as it plainly existed at the time when the decimal system was still dominant. As the latter was the system which prevailed among the Indians of the Vedic period there was no reason why they should borrow the Chaldaean term. On the contrary there is rather a reason why the Chaldaeans would have borrowed the term from India. Gold did not pass into India from Babylonia, for as we have already seen there are no auriferous strata in Mesopotamia, but it passed from the rich surface deposit of the valley of the Oxus and Central Asia into Chaldaea. Now if the same term intimately associated with the same commodity is found among two different peoples, and it is known as a matter of certainty that one of these countries supplies the other with this particular article, there is a considerable probability that the peculiar term connected with the commodity has passed along with it from the source of its production into the country which imports it.
We saw above that there was no native gold in Chaldaea and therefore it must have been imported by those Chaldaean merchantmen from India by way of the Persian Gulf. But was there no gold in Chaldaea until the shipmen of Ur were able to construct vessels capable of a voyage, even albeit only a coasting voyage, to the mouths of the Indus? Working in metals must have been far advanced when such ships were built. That gold came from India we can have little doubt. But it probably came overland for ages before anything in the form of a ship larger than a ‘dug-out’ had ever floated on the Indian Seas.
