which was popularly ascribed to Divine revelation.[284] He finds many of the Babylonian characters the prototypes of Samaritan or Cuthean, and the similar Phoenician letters. Finally he shows with striking effect the wedge-like and angular origin of our own alphabetical system.[285] He called attention to the ancient custom of cutting inscriptions upon pillars and columns, and he considers it natural on that account to find that ‘the writing of the ancients was perpendicular rather than horizontal, columns and pillars being much fitter for the former manner of writing than for the latter.’[286] Such at least was the direction of the Egyptian, Ethiopian and Chinese. On account of the absence of stone in Babylon, it was necessary to substitute bricks, and we learn from Clement of Alexandria that Democritus took his treatise on Morals from an inscription written on a brick column.[287] The columnar origin of writing is perhaps the reason that the inscription on the Babylonian bricks is, as Hager asserts, ‘perpendicular rather than horizontal,’ an opinion he thinks he can prove by the gems he has studied. Various conjectures as to the subject of the legend on the bricks had been put forward. Münter and Grotefend thought it was a talisman;[288] others that it recorded some historical event or an astronomical observation; but Hager suggested that the subject was probably the same as that on the Roman bricks: that is to say, that it recorded the name and the place of the maker—a suggestion that turned out to be very nearly correct. He had no doubt that the writing was the same as that discussed by Democritus in his lost treatise, and which is referred to by many of the classical writers.[289] He considers that it is ideographic, ‘for we find single groups composed of abundance of nails, like the various strokes in the Chinese characters, all different from each other and different from the Persepolitan.’ Nor does he consider that they were developed from hieroglyphics, but deliberately ‘formed and combined by an arbitrary institution, and designed to express, not letters nor syllables, but either whole sentences or whole words.’[290] Finally he suggests that the Persepolitan mode of writing was directly derived from the Babylonian by simply laying the perpendicular inscription upon its side; by that means the heads of the wedges that were originally at the top are now all turned to the left, and the inscription that was originally read from top to bottom becomes by its changed position always read from left to right. ‘If we turn our perpendicular characters in such a manner as to make them lie in a horizontal direction, the effect will be exactly what takes place in the Persian writing.’[291] This is a remarkable anticipation of a much later discovery.
