Francis Aerssens, as we have seen, continued to be the Dutch ambassador after the murder of Henry iv. Many of the preceding pages of this volume have been occupied with his opinions, his pictures, his conversations, and his political intrigues during a memorable epoch in the history of the Netherlands and of France. He was beyond all doubt one of the ablest diplomatists in Europe. Versed in many languages, a classical student, familiar with history and international law, a man of the world and familiar with its usages, accustomed to associate with dignity and tact on friendliest terms with sovereigns, eminent statesmen, and men of letters; endowed with a facile tongue, a fluent pen, and an eye and ear of singular acuteness and delicacy; distinguished for unflagging industry and singular aptitude for secret and intricate affairs;—he had by the exercise of these various qualities during a period of nearly twenty years at the court of Henry the Great been able to render inestimable services to the Republic which he represented. Of respectable but not distinguished lineage, not a Hollander, but a Belgian by birth, son of Cornelis Aerssens, Grefter of the States-General, long employed in that important post, he had been brought forward from a youth by Barneveld and early placed by him in the diplomatic career, of which through his favour and his own eminent talents he had now achieved the highest honours.
He had enjoyed the intimacy and even the confidence of Henry iv., so far as any man could be said to possess that monarch’s confidence, and his friendly relations and familiar access to the King gave him political advantages superior to those of any of his colleagues at the same court.
Acting entirely and faithfully according to the instructions of the Advocate of Holland, he always gratefully and copiously acknowledged the privilege of being guided and sustained in the difficult paths he had to traverse by so powerful and active an intellect. I have seldom alluded in terms to the instructions and despatches of the chief, but every position, negotiation, and opinion of the envoy—and the reader has seen many of them—is pervaded by their spirit. Certainly the correspondence of Aerssens is full to overflowing of gratitude, respect, fervent attachment to the person and exalted appreciation of the intellect and high character of the Advocate.
