Essex was married at age 13 to the 14-year-old Frances Howard; he was then sent on a European tour from 1607 to 1609, apparently without having consummated the marriage. Meanwhile, his wife began an affair with Robert Carr, Viscount Rochester, a favourite of King James I. After Essex's return, Frances sought an annulment on the grounds of impotence. Essex claimed that he was only impotent with her and had been perfectly capable with other women, adding that she "reviled him, and miscalled him, terming him a cow and coward, and beast." The divorce was a public spectacle and it made Essex a laughing-stock at court. It was small comfort that the finding that Frances was still a virgin was greeted with equal derision: as a popular ballad put it "The Dame was inspected, but fraud interjected a Maid of greater perfection." The annulment was granted on 25 September 1613, and Frances Howard married her lover, who had been made 1st Earl of Somerset, on 26 December 1613. Three years later the Somersets were tried by a panel of Lords for their part in the murder of Sir Thomas Overbury; Essex sat as a juror in the trial of his former wife and pressed the King to send her to the scaffold. Both were condemned to death, but the sentence was never carried out.
