Shakspere's dramatic career falls naturally into four successive divisions of increasing maturity. To be sure, no definite record of the order of his plays has come down to us, and it can scarcely be said that we certainly know the exact date of a single one of them; but the evidence of the title-page dates of such of them as were hastily published during his lifetime, of allusions to them in other writings of the time, and other scattering facts of one sort or another, joined with the more important internal evidence of comparative maturity of mind and art which shows 'Macbeth' and 'The Winter's Tale,' for example, vastly superior to 'Love's Labour's Lost'--all this evidence together enables us to arrange the plays in a chronological order which is certainly approximately correct. The first of the four periods thus disclosed is that of experiment and preparation, from about 1588 to about 1593, when Shakspere tried his hand at virtually every current kind of dramatic work. Its most important product is 'Richard III,' a melodramatic chronicle-history play, largely imitative of Marlowe and yet showing striking power. At the end of this period Shakspere issued two rather long narrative poems on classical subjects, 'Venus and Adonis,' and 'The Rape of Lucrece,' dedicating them both to the young Earl of Southampton, who thus appears as his patron. Both display great fluency in the most luxuriant and sensuous Renaissance manner, and though they appeal little to the taste of the present day 'Venus and Adonis,' in particular, seems to have become at once the most popular poem of its own time. Shakspere himself regarded them very seriously, publishing them with care, though he, like most Elizabethan dramatists, never thought it worth while to put his plays into print except to safeguard the property rights of his company in them. Probably at about the end of his first period, also, he began the composition of his sonnets, of which we have already spoken (page 119).
