The influences of Shakespeare's diction and versification upon those of the English drama in general can hardly be overrated, though it would be next to impossible to state them definitely. In these points, Shakespeare's manner as a writer was progressive; and this progress has been deemed sufficiently well traceable in his plays to be used as an aid in seeking to determine their chronological sequence. The general laws of this progress accord with those of the natural advance of creative genius; artificiality gives way to freedom, and freedom in its turn submits to a greater degree of regularity and care. In versification as in diction the earliest and the latest period of Shakespeare's dramatic writing are more easily recognizable than what lies between and may be called the _normal_ period, the plays belonging to which in form most resemble one another, and are least affected by distinguishable peculiarities--such as the rhymes and intentionally euphuistic colouring of style which characterize the earliest, or the feminine endings of the lines and the more condensed manner of expression common to the latest of his plays. But, such distinctions apart, there can be no doubt but that in verse and in prose alike, Shakespeare's style, so far as it admitted of reproduction, is itself to be regarded as the _norm_ of that of the Elizabethan drama; that in it the prose form of English comedy possesses its first accepted model; and that in it the chosen metre of the English versified drama established itself as irremovable unless at the risk of an artificial experiment.
