Not all things that come in small packages are undilutedly good. There are both many invigorating and some annoying aspects in this slim volume of chronologically arranged essays from Frank Kermode.
The best aspects arise when Kermode stays true to this title. That is, the book is finest when describing the milieu and preoccupations of Elizabethan England (or "Britain", since that distinction proves important to attitudes at the accession of James I) and relating those to the plays. Some of what struck me as the most interesting examples of this: Queen Elizabeth's belief that she was descended from the Roman Emperor Constantine and how that was reflected in "Antony and Cleopatra"; the issuing by King James in 1607 of a proclamation deploring crowds assembling "riotously in multitudes" and how that concern informs "Coriolanus"; and the customary conflating of "Macbeth" with the Gunpowder Plot enriched by a discussion of the play's use of the term "equivocation".
Among many fascinating aspects that go beyond the content of the plays, Kermode is especially informative about the distinction between the acting companies made up of boys and those of adult men players and the effect this had on many aspects of the theatrical environment. And there's his revelation that it was customary for the company to "dance a jig" after a play, even a tragedy.
Kermode's language is inventive and compelling, accessible for the most part even to someone -- like myself -- lacking knowledge of much of his context. Occasionally however his sentences become pretzel-like, circling back on themselves and becoming indigestible just when their meaning seems within grasp.
My primary and overarching complaint is that this is a small book (4 x 7, 214 pages). Some of the author's most interesting discussions are abbreviated by the limitations of the format. The publisher has nonetheless thought it just to price it at $21.95.
Like many in the seemingly hermetically-sealed world of Shakespearean scholarship, Kermode can not resist providing unjustifiable biographical details. Despite an early warning against it, we find tell-tale language such as "we may guess that", "was almost certainly", and "as he must have". He assures us that Shakespeare preferred horses to walking. And it may have been the limitations of the format that forced him to present as unarguable such disputatious concepts as the existence of an "ur-Hamlet" and that Robert Greene's attributed attack on "Shake-scene" was definitely referring to the author of the plays.
It's clear that Frank Kermode has a deep and unique understanding of both the plays and the times that produced them. "The Age of Shakespeare" allows him to, by apposing, illuminate them.
