His father, an old Leaguer, had been cognizant of his project, and had dissuaded him from it, but without doing anything to hinder it; he was banished from the kingdom for nine years, and from Paris forever.

His house was razed to the ground; and on the site was set up a pyramid with the decree of the Parliament inscribed upon it.
The proceedings did not stop there.

At the beginning of this same year, and on petition from the University of Paris, the Parliament had commenced a general prosecution of the order of Jesuits, its maxims, tendencies, and influence.

Formal discussions had taken place; the prosecution and the defence had been conducted with eloquence, and a decree of the court had ordained that judgment should be deferred.
Several of the most respected functionaries, notably President Augustin de Thou, had pronounced against this decree, considering the question so grave and so urgent that the Parliament should make it their duty to decide upon the point at issue.

When sentence had to be pronounced upon John Chastel, President de Thou took the opportunity of saying, "When I lately gave my opinion in the matter of the University and the Jesuits, I never hoped, at my age and with my infirmities, that I should live long enough to take part in the judgment we are about to pass to-day.
