Tracing the history of tragedy and comedy from their earliest beginnings to the present, this book offers readers an exceptional study of the development of both genres, grounded in analysis of landmark plays and their context. It argues that sacrifice is central to both genres, and demonstrates how it provides a key to understanding the grand sweep of Western drama. For students of literature and drama the volume serves as an accessible companion to over two millennia of drama organised by period, and reveals how sacrifice represents a through-line running from classical drama to todays reality TV and blockbuster movies. Across the chapters devoted to each period, Day explores how the meanings of sacrifice change over time, but never quite disappear. He charts the influences of religion, social change and politics on the status and purposes of theatre in each period, and on the drama itself. But it is through a close study of key plays that he reveals the continuities centred around sacrifice that persist and which illuminate aspects of human psychology and social organisation. Among the many plays and events considered are Aeschylus trilogy The Oresteia, Aristophanes Women at the Thesmorphia, Menanders The Bad-Tempered Man, the spectacles of the Roman Games, Senecas The Trojan Women, Plautuss The Rope, the Cycle plays and Everyman from the Middle Ages, Shakespeares King Lear and A Midsummer Nights Dream, Middletons The Revengers Tragedy, Jonsons Every Man in His Humour, Thomas Otways The Orphan, William Wycherleys The Country Wife, Wildes A Woman of No Importance, Beckett Waiting for Godot, Tennessee Williamss A Streetcar Named Desire, Suzan-Lori Parkss TopdogUnderdog, Sarah Kanes Blasted and Charlotte Jones Humble Boy. A conclusion examines the persistence of ideas of sacrifice in todays reality TV and blockbuster movies.
