Within recent years all has been done that can possibly be done to secure perfect copies of both Greek and Latin. In 1859 the Royal Academy of Berlin commissioned a scholar named Mordtmann to secure a _papier maché_ cast of the Latin, and to transcribe the Greek. He failed in both attempts, and declared that the casts would ruin the original. Napoleon III. commissioned George Perrot and Edmund Guillaume to explore Asia Minor. In their work above mentioned they give a facsimile copy of the whole of the Latin, and of as much of the Greek as they could get at. Their plates were the basis of an edition of the text by Mommsen in 1865, and another by Bergk in 1873, and of the text given in the _Corpus Inscriptionum Latinarum_. But Mommsen and the Berlin Academy were not satisfied. Carl Humann had distinguished himself by his researches at Pergamos, and to him they committed the task of securing casts of the whole of both texts. The story of his achievement is extremely interesting. Difficulty after difficulty was met and surmounted. And finally he succeeded in his plan. With materials dug near-by he made plaster casts. The owners of the Turkish houses he succeeded in inducing to allow their walls to be so far torn away as to permit him to get at the entire Greek text. And finally twenty great cases containing the whole series of casts were sent away on pack mules to the coast and thence to Berlin. The Royal Academy now counts these casts among its chief treasures. This was in 1882. In 1883 Mommsen published his great critical edition of the text, on which this edition is based. His work is almost final on the subject, but especially in the matter of conjectural fillings of the _lacunæ_ is subject to revision. But an inspection of the text as given in this volume will show that we have the words of Augustus almost in their entirety. At Apollonia, on the borders of Phrygia and Pisidia, has been found another ruined temple, with remnants of the Greek version of this inscription. At Apollonia the inscription originally covered seven pages. Of these there are still legible the upper portions of pages two, three, four and five. The correspondence between the text at Ancyra and that at Apollonia is almost exact, and where there is a divergence, it has been indicated. II. CHARACTER AND PURPOSE OF THE INSCRIPTION.
