For illustrative matter, I have made no effort to reproduce merely striking works of art, but have, for the most part, presented well-known works which readily illustrate the problems treated in the text. I have availed myself of collections of photographs kindly placed at my disposal by Professors Herbert E. Everett of the School of Fine Arts of the University of Pennsylvania, D. M. Robinson of the Johns Hopkins University, A. S. Cooley of the Moravian College at Bethlehem, Pennsylvania, and Dr. Mary H. Swindler of Bryn Mawr College. The various collections of plates and the books and journals from which I have taken illustrations are duly noted in the List of Illustrations.
In addition, I wish to thank the following corporations and individuals for permission to reproduce plates and text-cuts from the works cited: the Council of the Society for the Promotion of Hellenic Studies, of London, for the use of four plates appearing in the _Journal of Hellenic Studies_ (Figs. 44, 54, 55, and 59); the Trustees of the British Museum in London for seven plates from _Marbles and Bronzes in the British Museum_ (Pls. 7A, 17, 19; Figs. 14, 28, 31, and 35); Professor E. A. Gardiner and his publishers, Duckworth and Co., of London, for two plates from _Six Greek Sculptors_ (Pl. 30; Fig. 71); Mr. H. R. Hall, of the British Museum, and his publisher, Philip Lee Warner, of London, for one from _Aegean Archæology_ (Fig. 1); Professor Allan Marquand, of Princeton University, for one text-cut from the _American Journal of Archæology_ (Fig. 49), and Dr. J. M. Paton, former editor-in-chief, for three other text-cuts from the same journal (Figs. 70, 72, 79).
To the following I am also indebted for individual photographs: Dr. J. N. Svoronos, Director of the Numismatic Museum, Athens, Greece, for one of the oldest-dated statues of an Olympic victor (Fig. 79), which has already appeared in the _American Journal of Archæology_; Dr. A. Fairbanks, of the Museum of Fine Arts, Boston, for those of the statue of a Charioteer (?) and of the fragmentary head of the _Oil-pourer_ (Pl. 27; Fig. 23); Dr. Edward Robinson, of the Metropolitan Museum of Art, New York, for those of the fine Kresilæan and Praxitelian heads (Pls. 15, 20), and of the bronze statuette of a diskobolos (Fig. 46); Prof. Alice Walton, of Wellesley College, for one of the Polykleitan athlete (Pl. 13); the Director of the Fogg Art Museum of Cambridge, Mass., for that of the so-called _Meleager_ (Fig. 77); Dr. S. B. Luce, recently of the Museum of the University of Pennsylvania, for photographs of two vase-paintings showing athletic scenes (Figs. 50, 56), and Dr. Eleanor F. Rambo, formerly of the same Museum, for a copy of the Knossos wall-painting (Pl. 1).
