F. Allen's History of Rome, which is to be issued soon, and it is to his courtesy that I am indebted for their use.
The illustrations have been carefully selected with reference to their authenticity and historical truthfulness. Many of those in the Oriental and Greek part of the work are taken from Oscar Jäger's Weltgeschichte; while most of those in the Roman portion are from Professor Allen's forthcoming work on Rome, to which I have just referred, the author having most generously granted me the privilege of using them in my work, notwithstanding it is to appear in advance of his.
Further acknowledgments of indebtedness are also due from me to many friends who have aided me with their scholarly suggestions and criticism. My warmest thanks are particularly due to Professor W. F. Allen, of the University of Wisconsin; to Dr. E. W. Coy, Principal of Hughes High School, Cincinnati; to Professor William A. Merrill, of Miami University; and to Mr. D. H. Montgomery, author of The Leading Facts of History series.
July, 1889.
