The title of this book may strike the reader as strange and even dissonant. What have art and ritual to do together? The ritualist is, to the modern mind, a man concerned perhaps unduly with fixed forms and ceremonies, with carrying out the rigidly prescribed ordinances of a church or sect. The artist, on the other hand, we think of as free in thought and untrammelled by convention in practice; his tendency is towards licence. Art and ritual, it is quite true, have diverged to-day; but the title of this book is chosen advisedly. Its object is to show that these two divergent developments have a common root, and that neither can be understood without the other. It is at the outset one and the same impulse that sends a man to church and to the theatre.

Such a statement may sound to-day paradoxical, even irreverent. But to the Greek of the sixth, fifth, and even fourth century B.C., it would have been a simple truism. We shall see this best by following an Athenian to his theatre, on the day of the great Spring Festival of Dionysos.
