First published in 1577, this document — heavily mined by Shakespeare for his histories — is silent as to the further particulars of the beheading. But the accompanying image depicting the execution surprisingly presents a guillotine-like device being employed for the task.
As John Wilson Croker’s History of the Guillotine observes, this one illustration 270 years after the fact scarcely suffices to establish that a guillotine precursor really was in use in Ireland in the first years of the 14th century. Were that the case, this might be the earliest quote-unquote “documented” execution by a beheading-machine.
(Executions in Halifax, Scotland, can be sourced as early as the 1280s, but it is not known if the famed Halifax Gibbet was in use at that early date.)
But it does at least establish the authors’ awareness of such technology — perhaps by familiarity with the Scottish Maiden, or perhaps by having caught wind of similar gadgets in France and Italy.
“This mode of execution was common on the Continent in the sixteenth and seventeenth centuries,” Croker concludes with a bit of overstatement. “And yet had passed into such entire desuetude and oblivion as to have appeared as a perfect novelty when proposed by Dr. Guillotin.”
“This is certainly a striking illustration of the proverb that there is nothing new under the sun.”
