He starts with the advantage of a strong framework. His book covers the years from 1865 to 1965, when the proscenium theatre was dominant, and deals with more than 70 playwrights. Today we celebrate the limitless possibilities of theatre with open, apron, traverse and circular stages but Dromgoole enthuses over a time when plays were mainly enclosed behind a proscenium arch. He describes the form as “liberatingly restrictive” like the 14-line sonnet or the 12-bar blues and he has a point.
We associate the proscenium with the good-mannered, well-made play but it also gave birth to Chekhov’s work for the Moscow Art theatre, Brecht’s revolutionary ideas in East Berlin and, closer to home, Joan Littlewood’s radical populism at the Theatre Royal Stratford East and the explosion of energy at the Royal Court. Seizing on the closely crafted, socially critical plays of John Galsworthy, Dromgoole says they are perfect examples of the proscenium paradox: “entertainment encasing dysfunction”.

Inevitably there are moments when one wants to argue with Dromgoole. For me that came when he attacks Ibsen for his lack of humour and, having trawled through the plays, says there is “a fatal lack of jokes”. I agree there are few one-line zingers in Ibsen but his plays are permeated by comic irony. I even laugh aloud towards the end of The Wild Duck when Hjalmar says he can’t stay a moment longer in a house poisoned by lies but is persuaded by his wife to have some breakfast before he goes. What of Pastor Manders in Ghosts whose unworldly naivety provokes the giggles in Mrs Alving? And even though An Enemy of the People is about the fatal compromises in a spa town whose wealth depends on toxic water, there is something comic about Dr Stockmann’s advice about what trousers to wear before addressing a public meeting. If modern Ibsen productions have shown us anything it is that he is one of theatre’s hidden humorists.
But I don’t want to cavil at a book that re-assesses the work of familiar writers such as Oscar Wilde, George Bernard Shaw and Brendan Behan, draws attention to neglected ones including Gerhart Hauptmann, Arthur Schnitzler and Susan Glaspell and makes use of Dromgoole’s experience as a director. There is a particularly poignant passage where he sees Harold Pinter downing a quiet, solitary pint at the Bush theatre in the 1990s before being forced to resume his public persona. But, although Dromgoole is by profession a director he is passionate in his advocacy of the dramatist. When he says of devised texts “there remains something flavourless without a writer, some lack of texture and the music of heard life” I wanted to fling my hat in the air and cheer.
