objects must have had natural markings on them which would have left impressions on the clay, while these impressions, we can hardly doubt, were early noticed by the primitive store owner, and their condition served to tell him whether or not his closed jars had been tampered with. In this connection it is interesting to note that Aristophanes (Thesmo., 424-428), when referring to the custom of securing doors by sealing them, alludes to certain [Greek: thripêdesta sphragidia], which were worm-eaten bits of wood used as rude seals. He speaks of them as having supplanted the simple seals of olden days, but they ought rather to be considered as a return to the early type of “reed” seal. (Muller, _Archäol., I. Kunst._, 97, 2.) From the natural markings upon the objects employed to smooth the clay, the transition was easy to some definite device scratched around the circumference of the stick or reed, or upon the surface of the stone or pebble, by the owner, and appropriated to himself as his own peculiar mark. But as these markings or devices would have had little weight with a determined thief, we can hardly doubt that, in Babylonia at any rate, they became early imbued with a _magical_ signification: so that their real power would be moral rather than physical. The reasoning of the lawyers of the Middle Ages regarding the sealing of contracts was that a _seal_ attracts and excites caution in illiterate persons, and thereby operates as a security against fraud.[5] The simple scratchings that we find on so many of the early Egyptian pots were the possessors’ marks; indeed, King contends that “this instinct of possession extending itself to the assumption of exclusive ownership in certain configurations of lines, or rude delineations of natural objects, is a universal impulse of man’s nature, and one found existing amongst all savage nations when first discovered, wheresoever the faintest trace of social life and polity have begun to develop themselves.” A great number of these signs Professor Petrie has preserved in his various records of explorations. (_Cf._ his _Naqada_, p. 44.) Thus the Red Indian has besides the tribal mark, that of the individual (his special _totem_), wherewith to identify his own property, or the game he may kill. The South Sea Islander carries the tattooed pattern that distinguishes his particular family, imprinted upon his own skin, and also draws the same upon his credentials like a regular coat of arms. It is therefore in these markings firstly scratched on pots, and next on rude seals, that we have the very beginnings of writing; but a long period probably elapsed before these primitive signs were combined together to form words. The designs on these seals were probably at first rough configurations of lines, which sufficiently served their purpose if they could be readily identified by the owner; but after a time these primitive figures seem to have given
