The historical allusions in Sonnets c.-cxxvi., which form a continuous poem, are not, indeed, by any means clear or easy to interpret; but Sonnet civ. dates the whole group definitely enough, in the statement that three years have elapsed since the first meeting of the friends:—
"Three winters cold
Have from the forests shook three summers' pride;
Three beauteous springs to yellow autumn turn'd
In process of the seasons have I seen;
Three April perfumes in three hot Junes burn'd,
Since first I saw you fresh, which yet are green."
Thus we must assign this important group to the year 1601; and this being so, it must also appear probable that the line—
"The mortal moon hath her eclipse endured "—
alludes to the fact that Elizabeth (for whom, in the mode of the day, the moon was the accepted symbol) had come unharmed through the dangers of Essex's rebellion—the more so as the beautiful lines—
"Now with the drops of this most balmy time
My love looks fresh "—
show that the poem was written in the spring. It would be unreasonable to infer from this allusion any ill-will on the poet's part towards Essex and his comrades. Still less can we follow Tyler, when, by the aid of a complex scaffolding of hypotheses built up, in German rather than in English fashion, around Sonnets cxxiv. and cxxv., he laboriously works up to the air-drawn conjecture that Shakespeare is here expressing himself offensively towards his former patron Southampton, now a prisoner in the Tower, and even that Southampton is aimed at in the line about those "who have lived for crime." Equally baseless, of course, is the corollary which would find in Sonnet cxxv. Shakespeare's defence against an accusation of faithlessness towards the man to whom he had written, seven years earlier, in the dedication of Lucrece, "The love I dedicate Your Lordship is without end." Nor It is absurd to construct a whole repulsive and fantastic romance on the basis of a single obscure phrase.
Turning now from the poems to the person to whom they are believed to have been addressed, this is what we learn of him:—
William Herbert, son of Henry Herbert and his third wife, the celebrated Mary Sidney, had for his tutor as a boy the poet Samuel Daniel; entered at Oxford in 1593, where he remained for two years; received permission in April 1597, when he was seventeen years old, to live in London, but, as we gather from letters of the period, does not seem to have come up to town until the spring of 1598.
In August 1597, negotiations were conducted by letter between his parents and Lord Burghley with a view to his marriage with Burghley's grand-daughter Bridget Vere, a daughter of the Earl of Oxford. It is true that she was only thirteen, but William Herbert was quite prepared to enter upon the engagement. He was to travel abroad before the marriage. Although his mother, the Countess of Pembroke, perhaps divining her son's too in flammable nature, and therefore wanting to see him married betimes, was much in favour of this project, and although the Earl of Oxford was pleased with the young man and praised his "many good partes," difficulties arose of which we have no record, and the plan came to nothing.
