(Tragic Prelude by John Steuart Curry)
Today marks the 150th anniversary of the hanging of abolitionist John Brown. Brown's failed 1859 attack on the federal armory at Harpers Ferry was a major catalyst of the American Civil War. Brown's sealed his role as a martyr by proclaiming prior to his execution that, "I, John Brown, am now quite certain that the crimes of this guilty land will never be purged away but with blood."
