Four Periods of his Life.--We may make another classification from a different point of view, according to the period of his development at the time of writing special plays. In order to study his growth and changing ideals, it will assist us to divide his work into four periods. (1) There was the sanguine period, showing the exuberance of youthful love and imagination. Among the plays that are typical of these years are _The Comedy of Errors, A Midsummer Night's Dream, Romeo and Juliet, Richard II._, and _Richard III_. These were probably all composed before 1595. (2) The second period, from 1595 to 1601, shows progress in dramatic art. There is less exaggeration, more real power, and a deeper insight into human nature. There appears in his philosophy a vein of sadness, such as we find in the sayings of Jaques in _As You Like It_, and more appreciation of the growth of character, typified by his treatment of Orlando and Adam in the same play. Among the plays of this period are _The Merchant of Venice, Henry IV., Henry V.,_ and _As You Like It_. (3) We may characterize the third period, from 1601 to 1608, as one in which he felt that the time was out of joint, that life was a fitful fever. His father died in 1601, after great disappointments. His best friends suffered what he calls, in _Hamlet,_ "the slings and arrows of outrageous fortune." In 1601 Elizabeth executed the Earl of Essex for treason, and on the same charge threw the Earl of Southampton into the Tower. Even Shakespeare himself may have been suspected. The great plays of this period are tragedies, among which we may instance _Julius Caesar, Hamlet, Othello, Macbeth,_ and _King Lear_. (4) The plays of his fourth period, 1608-1613, are remarkable for calm strength and sweetness. The fierceness of _Othello_ and _Macbeth_ is left behind. In 1608 Shakespeare's mother died. Her death and the vivid recollection of her kindness and love may have been strong factors in causing him to look on life with kindlier eyes. The greatest plays of this period are _Cymbeline, The Winter's Tale_, and _The Tempest_. While the dates of the composition of these plays are not exactly known, the foregoing classification is probably approximately correct. It should be followed in studying the development and the changing phases of Shakespeare's mind. (See table, pp. 188 and 189.)
