By the time Shakespeare came to write Macbeth - almost certainly in 1605/1606 - he had already completed three of the great tragedies with which modern audiences are so familiar: Hamlet (1601), Othello (1603), and King Lear (1605). Each of those plays gives us an eponymous hero who is in some significant way flawed, but for whom we also inevitably feel deep sympathy, whatever his errors or crimes. But in MacBeth, Shakespeare has chosen for his tragic hero a man guilty of the most terrible crime imaginable to a Jacobean audience, that of regicide - the murder of a king.

Distressed by his father's death and his mother's over-hasty remarriage, Hamlet, Prince of Denmark, is faced by a specter from beyond the grave bearing a grim message of murder and revenge. The young prince is driven to the edge of madness by his struggle to understand the situation he finds himself in and to do his duty. Many others, including Hamlet's beloved, the innocent Ophelia, are swept up in his tragedy.

This shattering drama of isolation and loss is one of the greatest tragedies in world literature. King Lear of Britain has three daughters: the hard-hearted Goneril and Regan, and the good and gentle Cordelia. He determines to divide his kingdom between them, giving the largest share to she who can say she loves him the best. Lear's tragic lack of judgment and self-knowledge is paralleled by the blindness of the loyal Gloucester who is persuaded to reject his virtuous son, Edgar, in favor of the villainous Edmund.

Written initially in French, later translated by the author into English, Molloy is the first book in Dublin-born Samuel Beckett's trilogy. It was published shortly after WWII and marked a new, mature writing style, which was to dominate the remainder of his working life. Molloy is less a novel than a set of two monologues narrated by Molloy and his pursuer, Moran.

There is now no doubt that not only is Waiting for Godot the outstanding play of the 20th century, but it is also Samuel Beckett's masterpiece. Yet it is both a popular text to be studied at school and an enigma. The scene is a country road. There is a solitary tree. It is evening. Two tramp-like figures, Vladimir and Estragon, exchange words. Pull off boots. Munch a root vegetable. Two other curious characters enter. And a boy. Time passes. It is all strange yet familiar.
