"has said that 'a little knowledge is a dangerous thing.' Compared with much knowledge, it may be; but it is a vast deal better than no knowledge. Here is a case in point. I have read with very keen interest the wonderful history of the decipherment of the cuneiform writing, and I happen to recollect one or two of the main facts that seemed to me to be worth remembering. This particular inscription is in the Persian cuneiform, a much more simple and open form of the script than the Babylonian or Assyrian; in fact, I suspect that this is the famous inscription from the gateway at Persepolis—the first to be deciphered; which would account for its presence here in a frame. Now this script consists, as you see, of two kinds of characters; the small, solid, acutely pointed characters which are known as wedges, and the larger, more obtuse characters, somewhat like our government broad arrows, and called arrow-heads. The names are rather unfortunate, as both forms are wedge-like and both resemble arrow-heads. The script reads from left to right, like our own writing, and unlike that of the Semitic peoples and the primitive Greeks; and the rule for the placing of the characters is that all the 'wedges' point to the right or downwards and the arrow-head forms are open towards the right. But if you look at this photograph you will see that all the wedges point upwards to the left and that the arrow-head characters are open towards the left. Obviously the photograph is upside down."
