For many, many years, the printers in the different countries used Alphabets the artists had made for them, without being able to decide which they liked the best, the Roman, Gothic or Italic. On Plate VIII you will find a little poem by Shakespeare printed in these three Alphabets. Which one do you like the best? I am sure you will choose the one that is the simplest, the easiest to read and at the same time the most beautiful--the Roman. In the quarrel which had been going on for so many years, the Roman alphabet won the victory, and that is how it came about that the Roman is used in printing all our newspapers and books today. At last after so many hundreds of years it has traveled through the other countries to us. Many times you cannot recognize the letters, and they look very different from the Roman models from which they were patterned, but that is because we are not as careful with the measurements and proportions as were Albert Duerer and the other Masters in that time long ago. CHAPTER III You know now the beginning of the Alphabet, the careful way it was planned and made, and how finally after so many years it has come to be used in the form in which we have it today. Do you remember that when Albert Duerer made his Alphabet of Roman letters he made more than one form of each letter--there were three _A_'s, for example. Would you like to know why he did this? Plate IX shows you two other kinds of Alphabets made long ago by a Spanish artist, Francisco Lucas. Look at the Italic capital letters in the upper part of this Plate. You can easily see that there are two different forms of the same letters, can you not? But now look at the small letters. You still see that there are two examples of each letter, but they are so much alike that you will have to look very carefully to see the difference between the two forms. Why do you suppose this artist went to the trouble to make these letters so much alike, and yet different? Do you not think that this would be a very strange thing to do unless there was a good reason for it? Look at the lower part of the Plate and you will see that there are two different forms of the small Roman letters also. Now turn back to Lesson XV. You see that by using a capital letter for the _a_ form and a small letter for the _b_ form you were able to hide within the phrase "_Biliteral Cipher_" the word, "_key_." You can easily see that this would not be a good way to hide a secret, for the difference between the large and small letters is not only easy to see, but looks so strange that it is the first thing you notice. Now suppose that instead of using a capital letter for the _a_ form and a small letter for the _b_ form you use for each letter of the Alphabet, both capital and small, two forms which were very much alike but still were different.
