It has been said that Lady Raleigh kept her husband's head in a velvet bag until her death

Sir Walter Raleigh was a fascinating historical personage. From Wikipedia, vignettes surrounding his execution.

Raleigh was beheaded in the Old Palace Yard at the Palace of Westminster on 29 October 1618. "Let us dispatch", he said to his executioner. "At this hour my ague comes upon me. I would not have my enemies think I quaked from fear." After he was allowed to see the axe that would be used to behead him, he mused: "This is a sharp Medicine, but it is a Physician for all diseases and miseries." According to biographers, Raleigh's last words (as he lay ready for the axe to fall) were: "Strike, man, strike!"

Thomas Hariot may have introduced him to tobacco. Having been one of the people to popularise tobacco smoking in England, he left a small tobacco pouch, found in his cell shortly after his execution. Engraved upon the pouch was a Latin inscription: Comes meus fuit in illo miserrimo tempore ("It was my companion at that most miserable time").

His wife was something of a character as well.

Raleigh's head was embalmed and presented to his wife. His body was to be buried in the local church in Beddington, Surrey, the home of Lady Raleigh, but was finally laid to rest in St. Margaret's, Westminster, where his tomb may still be visited today. "The Lords", she wrote, "have given me his dead body, though they have denied me his life. God hold me in my wits." It has been said that Lady Raleigh kept her husband's head in a velvet bag until her death. After Raleigh's wife's death 29 years later, his head was returned to his tomb and interred at St. Margaret's Church.
