The number of books, treatises, and articles which have been written on the subject during the last few years is so great that it would be impossible to mention them all. I propose in the following list to specify only those which I have found most useful, and to which I am chiefly indebted. Many others will be referred to in the notes. The most important work of recent years on the Greek theatre is Dörpfeld and Reisch’s _Das griechische Theater_ (Athens, 1896). The admirable and exhaustive account of the Theatre of Dionysus at Athens, which is given in this book, has superseded all previous descriptions. Dörpfeld appears to have now proved conclusively that the stone theatre at Athens was not earlier than the fourth century B.C., and his views on the subject have been followed in the present edition. The book also contains a valuable summary of the chief points of interest in other theatres recently excavated, and a complete exposition of Dörpfeld’s theory about the Greek stage. Some further developments and modifications of this theory will be found in two articles lately published by Dörpfeld in the _Bulletin de Correspondance Hellénique_, 1896, p. 563 ff., and in _Athenische Mittheilungen_, 1897, p. 439 ff. After reading through Dörpfeld’s arguments, and those of other scholars who support his views, I am still of opinion that the old theory is the right one, and that the Greek actors performed on a stage from the first; though no doubt the stage of the fifth century was much lower than that of later times. Among other writings which deal with the subject of the Greek theatre as a whole I may mention the following:—Oehmichen, _Das Bühnenwesen der Griechen und Römer_, München, 1890; Navarre, _Dionysos_, Paris, 1895 (a lucid and well-written summary); the valuable articles by Prof. Jebb in Smith’s _Dictionary of Antiquities_ (v. _Theatrum_), and by Prof. P. Gardner in Jevons and Gardner’s _Manual of Greek and Roman Antiquities_; and Bethe’s _Prolegomena zur Geschichte des Theaters im Alterthum_, Leipzig, 1896. This last book, though often rather fanciful in its conclusions, is full of useful information and interesting suggestions.
