Now, if it be deemed necessary that I should forfeit my life for the furtherance of the ends of justice, and mingle my blood further with the blood of my children, and with the blood of millions in this slave country whose rights are disregarded by wicked, cruel, and unjust enactments, I submit: so let it be done.
John Brown, American abolitionist, born on May 9, 1900; speaking in court before being sentenced to death

Festival of the Lemuria, Festival of Ghosts, ancient Rome (also 11th and 13th May)
Lemures were wandering spirits of the departed. They were said to revisit their homes at this time, and were shown respect by the Roman people, who set aside a week to appease them.

At midnight, each household’s male head would wash his hands in spring water, then throw away one black bean for each resident of the household. He then washed his hands again, and clashed bronze cymbals together to summon the spirits. This ritual was repeated on the 11th and 13th of this month.
