Erazm Otwinowski (1529âÂÂ1614) was a Polish Renaissance poet, Calvinist and Socinian activist.
Born at Lià Ânik Duà ¼y, Poland to a noble family. He was sent as a boy to the Wià Ânicz Castle where he received his early education. There he came in contact with Protestants. Later he served for a Polish magnate Stanisà Âaw TÃÂczyà Âski (important propagator of Reformation in Poland) as secretary and diplomat. TÃÂczyà Âski sent him with many diplomatic missions abroad (e.g. to Turkey, Sweden, and Denmark).
In 1555 Otwinowski adopted Calvinism, but after 1570 until his death became an ardent supporter of the nontrinitarian Polish Brethren Church. In 1564 he became famous because of his public âÂÂblasphemyâ against the Catholic doctrine of Transubstantiation during the Corpus Christi procession in Lublin.
After TÃÂczyà ÂskiâÂÂs death in 1561, Otwinowski returned to Poland for good, where he remained active as a humanist, theologian, and Renaissance poet. He wrote numerous Polish-language verse forms (many were lost afterwards) based on biblical, social, and erotic motives. He died in poverty in his estate in Lià Ânik Duà ¼y.
