Dionysos is one of the most-studied ancient Greek gods for students and academics. He is popularly known as the god of wine and frenzied abandon, and has great significance for theatre -- drama, in fact, originated as part of the cult of Dionysos. However, Seaford's book covers a wider range of issues, such as mystery, cult and philosophy, which have been overlooked by many studies. As a volume in the Gods and Heroes series, this work will provide an indispensable introduction to the subject, or reference point for higher levels of study.
