On January 19, 1601, his father's death made William Herbert Earl of Pembroke. Very soon afterwards (the matter is mentioned in a letter from Robert Cecil so early as February 5) he got into deep disgrace over a love affair--evidently that which forms the subject of Shakespeare's Sonnets. He had for some time carried on a secret intrigue with the aforesaid Mary Fitton, a maid-of-honour who stood high in the Queen's good graces; and the secret now came to light. "Mistress Fitton," writes Cecil, "is proved with child, and the Earl of Pembroke, being examined, confesseth a fact, but utterly renounceth all marriage. I fear they will both dwell in the Tower awhile, for the Queen hath vowed to send them thither." In another contemporary letter it is stated that "in that tyme when that Mres Fytton was in great fauor ... and duringe the time yt the Earle of Pembrooke fauord her, she would put off her head tire and tucke vp her clothes and take a large white cloake, and march as though she had bene a man to meete the said Earle out of the Courte." Mary Fitton gave birth to a still-born son; Pembroke lay for a month in the Fleet Prison, and was banished from Court. He shortly afterwards applied through Cecil for leave to travel abroad. The Queen's displeasure, he says, is "a hell" to him; he hopes the Queen will not carry her resentment so far as to bind him to the country which has now become "hateful to him of all others." The permission to travel seems to have been given and then revoked. In the middle of June he writes that imploring letter to Cecil in which the reference to "her whose Incomparable beauty was the onely sonne of my little world," was designed to touch Elizabeth's hard heart; for Pembroke, it is plain, had now realised that what had offended her Majesty was not so much his intrigue with Mary Fitton as the fact of his having overlooked her own much higher perfections. But the compliments came too late. Elizabeth, as we have already seen in the case of Essex, knew how to make the objects of her resentment suffer in that most sensitive point--the pocket. The "patent of the Forest of Dean," which had been held by the late Lord Pembroke, expired with him, and the son expected, according to use and wont, to have it renewed in his favour; but it was assigned to Pembroke's rival, Sir Edward Winter, and not until seven years later, under James, did Pembroke recover it. Pembroke continued in disgrace, his renewed applications for permission to travel were persistently refused, and he was ordered to regard himself as banished from Court, and to "keep house in the country." It is this overshadowing of Pembroke's fortunes in 1601 which explains the temporary breaking-off of his relations with Shakespeare in London, indicated by the "Envoy" with which Sonnet cxxvi. ends the series addressed to the Friend.
