On Monday, 13 May 1619, the death sentence was read to Van Oldenbarnevelt and the same morning the old statesman, at the age of seventy-one, was beheaded in the Binnenhof, in The Hague. His last words to the gathered crowd were: "Men, do not believe I am a traitor, I have acted sincerely and piously, as a good patriot, and I shall die this way." Van Oldenbarnevelt's last words to the executioner were purportedly: "Make it short, make it short." He was buried under the Court Chapel (Hofkapel) at the Binnenhof. During Van Oldenbarnevelt's captivity his servant Jan Francken kept a diary, forty pages long at the time of his execution; a copy was made in 1825 for wider dissemination, but the original then disappeared until it was rediscovered in 2018. The States of Holland noted in their Resolution book, on 13 May, that Van Oldenbarnevelt had been: "…a man of great business, activity, memory and wisdom – yes, extra-ordinary in every respect." They added the sentence "Die staet siet toe dat hij niet en valle", "He who stands, let him take care that he does not fall", which is a quotation from, which probably should be understood as referring to both how Van Oldenbarnevelt ended after holding one of the highest offices in the Republic and for choosing the side of the Arminians, who were ruled to be standing outside the Dutch Reformed Church and the Reformed Faith by the Synod of Dort. Van Oldenbarnevelt left two sons: Reinier van Oldenbarnevelt, lord of Groeneveld and Willem van Oldenbarnevelt, lord of Stoutenburg, and two daughters. A conspiracy against the life of Maurice, in which both sons of Van Oldenbarnevelt took part, was discovered in 1623. Stoutenburg, who was the chief accomplice, made his escape and entered the service of Spain; Groeneveld was executed. In London, "The Tragedy of Sir John van Olden Barnavelt", a Jacobean play by John Fletcher and Philip Massinger, was written and produced within three months of its protagonist's execution. Being controversial in terms of English as well as Dutch politics, it suffered considerable censorship before being allowed on the stage. The Nederland Line ship "Johan van Oldenbarnevelt" carried his name from 1930 to 1963.
