Sethe has gone over the field again in a series of articles which deserve all praise: ‘Der Ursprung des Alphabets,’ in Nachrichten, Göttingen Academy, Geschäftliche Mitteilungen, 1916, 88–161Google Scholar; ‘Die Neuentdeckte Sinai-Schrift und die Entstehung der semitischen Schrift,’ Ibid., 1917, 437–475; ‘Die wissenschaftliche Bedeutung der Petrie'schen Sinaifunde,’ ZDMG, 80, 24 ff. The older works of Praetorius should not be forgotten. More recently Jensen, Hans has published his Geschichte der Schrift, Hannover, 1925Google Scholar; see the bibliography there given. To forestall misunderstanding of the necessarily controversial discussion of technical questions which follows in the present article, I would emphasize that the criticism by other scholars of Grimme's translation of the inscriptions has given to many an inadequate impression of the value of the rest of his work. His application of genuine scholarship to the problem has shown the way to further progress, and from his publications on the Sinai inscriptions there is much to be learned.
