In the Metropolitan Museum of Art in New York are Babylonian tablets bearing distinct records of credit transactions that took place in the reign of Nebuchadnezzar. The earliest tablet is of the year 601 B.C. On it are memoranda of loans of silver made by Kurdurru as follows: "1 mina of silver to Suta, 1 mina to Balludh, 1/2 mina to Buluepus, 5 shekels to Nabu-basa-napsate, and 5 shekels to Nergal-dann;--total, 3 minas, 5 shekels of silver." There are more than 50 similar tablets in this collection; the latest dated, "Babylon, 18th day of 14th year of Darius," that is, B.C. 505. M. Lenormant, who can read them, divides these credit documents into five principal types. 1. Simple obligations; 2. Obligations with a penal clause in case of non-fulfilment; 3. Obligations with the guarantee to a third party; 4. Obligations payable to a third person; and 5. Drafts drawn upon one place, payable in another. These last are letters of Credit. They contain the names of several witnesses. They are evidently negotiable, but from the nature of things could not pass by indorsement, because when the clay was once baked nothing new could be added, and under these circumstances the name of the payee was often omitted. It seems to follow from this peculiarity, that the drawee must have been regularly advised by the drawer. One of the credits in this most interesting collection had 79 days to run. The main elements of their civilization came to the Greeks, and especially to the Greek cities in Asia Minor demonstrably from the Eastward; the Greek West proved itself quick to catch up the thoughts and the modes of the East; accordingly, Isocrates in his plea against the banker, Pasion, describes a formal bill of Exchange bought by Stratocles in Athens, payable in Pontus, and guaranteed principal and interest by Pasion; the practical Romans were pupils of the Greeks in all such matters, and so it came about in course of time, that Cicero wrote as follows in a letter to Atticus,--"Let me know, if the money my son needs at Athens can be sent him _by way of exchange_, or if it be necessary for it to be taken to him,--_permutarine possit an ipsi ferendum sit_"; and after that the Jews and the Lombards carried the Letter of Credit all over the world. It goes without saying, when the most civilized and advanced people of the world were the first to adopt and have been since the quickest to expand the use of Credit, that there must be pretty obvious and very solid advantages from such use and expansion; and we must now note and weigh a few of these advantages.
