Hieronim Moskorzowski or Moskorzewski, also known as Moscorovius, Jarosz Moskorzowski, pseudonymy: Eusebius, Medicus, Nobilis, Subditus Fidelis (c. 1560 in Moskorzew – 1625 in Raków, Kielce County) was an administrator of the Racovian Academy, writer, polemicist, and member of the Polish Brethren. Biography Moskorzowski was born in 1560 in Moskorzew, near Szczekocin. He came from a noble family, received a comprehensive education, and became involved with the movement of the Polish Brethren. Unlike the older generation of the Ecclesia Minor he was involved in politics and as a member of the Sejm repeatedly defended the rights of minority believers and dissenters there. At the zjazd meeting of the nobility in Lublin (4 June 1606) he objected to the revolt of the nobility against the king and senators, and was elected to the committee that put together the articles of a request for nobles to the king. He spent time in Gdańsk in 1610, and in 1611 was delegated to the Lithuanian provincial synod. He participated in the Zebrzydowski Rebellion. He married Regina Dudycz, daughter of Andreas Dudith. Works He prepared the Polish and Latin text of the 1605 Racovian Catechism, which Fausto Sozzini, who died in 1604, did not manage to complete. He worked together with Piotr Stoiński Jr. and Jan Völkel. In 1605, Moskorzowski translated the Cathecism into Latin.
