At a somewhat later period Professor Erpenius, publishing a new edition of the New Testament in Greek, with translations in Arabic, Syriac, and Ethiopian, solicited his friend’s help both in translations and in the Latin commentaries and expositions with which he proposed to accompany the work.  The prisoner began with a modest disclaimer, saying that after the labours of Erasmus and Beza, Maldonatus and Jasenius, there was little for him to glean.  Becoming more enthusiastic as he went on, he completed a masterly commentary on the Four Evangelists, a work for which the learned and religious world has ever recognized a kind of debt of gratitude to the castle of Loevestein, and hailed in him the founder of a school of manly Biblical criticism.

And thus nearly two years wore away.  Spinning his great top for exercise; soothing his active and prolific brain with Greek tragedy, with Flemish verse, with jurisprudence, history, theology; creating, expounding, adorning, by the warmth of his vivid intellect; moving the world, and doing good to his race from the depths of his stony sepulchre; Hugo Grotius rose superior to his doom and took captivity captive.  The man is not to be envied who is not moved by so noble an example of great calamity manfully endured.

The wife of Hoogerbeets, already advanced in years, sickened during the imprisonment and died at Loevestein after a lingering illness, leaving six children to the care of her unfortunate husband.  Madame de Groot had not been permitted by the prison authorities to minister to her in sickness, nor to her children after her death.

Early in the year 1621 Francis Aerssens, Lord of Sommelsdyk, the arch enemy of Barneveld and of Grotius, was appointed special ambassador to Paris.  The intelligence—­although hardly unexpected, for the stratagems of Aerssens had been completely successful—­moved the prisoner deeply.  He felt that this mortal enemy, not glutted with vengeance by the beheading of the Advocate and the perpetual imprisonment of his friend, would do his best at the French court to defame and to blacken him.  He did what he could to obviate this danger by urgent letters to friends on whom he could rely.

At about the same time Muis van Holy, one of the twenty-four commissioners, not yet satisfied with the misery he had helped to inflict, informed the States-General that Madame de Groot had been buying ropes at Gorcum.  On his motion a committee was sent to investigate the matter at Castle Loevestein, where it was believed that the ropes had been concealed for the purpose of enabling Grotius to make his escape from prison.

Lieutenant Deventer had heard nothing of the story.  He was in high spirits at the rumour however, and conducted the committee very eagerly over the castle, causing minute search to be made in the apartment of Grotius for the ropes which, as they were assured by him and his wife, had never existed save in the imagination of Judge Muis.  They succeeded at least in inflicting much superfluous annoyance on their victims, and in satisfying themselves that it would be as easy for the prisoner to fly out of the fortress on wings as to make his escape with ropes, even if he had them.
