In Paris Grotius expressed his gratitude for his wife's role in his escape with the Latin poem Silva ad Thuanum in which he made it known that the ruse with the chest had been invented by Maria.[1] Grotius soon unleashed a torrent of pamphlets and larger publications in which he defended Oldenbarnevelt and himself (the best-known is his Apologia or Verantwoordingh, published in Latin and Dutch in Paris in 1622). In the next decade he became an icon of the faction that would grow into the Dutch States Party.[1]
