Saint Hyacinth — called Saint Jacek in his native country — was one of the great saints of Poland. He has been called “the apostle of the North.” He traveled, preaching the Catholic Faith and bringing back to the Sacraments the peoples of Poland, Denmark, Sweden, Norway, and Russia. He even went over to China and converted some of the Chinese. He was a Dominican priest and is lovingly commemorated by all northern Christians. He was a direct disciple of Saint Dominic.
