On this date in 1441, the astrologer and mathematician Roger Bolingbroke was put to death as a wizard.
Bolingbroke had the ill luck to attach to the household of the Duchess of Gloucester at a juncture where it was politically convenient to destroy her; we have previously examined this affair through the person of Margery Jourdemayne, the Witch of Eye who with Roger Bolingbroke and a third man, Thomas Southwell, produced a horoscope for the Duchess prophesying King Henry VI‘s imminent demise — which was a bit on the nose for the king when he found out about it since at that moment the Duke of Gloucester would have stood to succeed him as king.
This exercise was nothing but an occult diversion, the medieval aristocracy’s equivalent of the Ouija board, but in the hands of enemies it became a treasonable plot for regicide. It forced the Duchess’s fall, divorce, and perpetual imprisonment — but what it forced for the commoners who scried the stars on her behalf was considerably worse. In the words of the Chronicle of London, Roger Bolingbroke
was taken for werchynge of sorcery ayens the king, and he was put into the Tour; and after, he was brought into Poules, and there he std up on high on a scaffold ageyn Poulys crosse on a Sonday, and there he was arraied like as he schulde never the in his garnementys, and there was honged rounde aboughte hym alle his intrumentis whiche were taken with hym, and so shewyd among all the peple; and after he was broughte to-fore the lordys, and there he was examyned; and after broughte to the Yeldehalle, and there he was regned aforen the lordes of the kynges counseill and to-fore alle the juges of this land; and anon after, the lady of Gloucestre afornseid was mad to apere thre sondry dayes afore the kyng and alle his lordes spirituell and temperell; and there she was examyned of diverses poyntes of wicchecraft, of the whiche she knowleched that she hadde used thorugh the counseil of the wicche of Eye, the whiche was brent on the even of Symond and Jude in Smythefeld.

* For present-day readers, this humiliating public penitential procession reminds of Cersei’s walk of atonement on Game of Thrones; however, the actual inspiration for this scene was the affair of a later 15th century Englishwoman, Jane Shore.
