The article is concerned with the handwritten cycle of poems "Głosy piąci zmysłów" [“Speeches of Five Senses”], that comes from the 2nd half of the 17th century. The text is part of a codex containing other rhetorical exercises by students of the Jesuit college in Orsza (Belarus). "Głosy piąci zmysłów" develop the issue of the Eucharistic mystery – voices of the five senses try to explore this problem and the Mind is their leader. But it turns out that four senses – eyesight, taste, the senses of touch and of smell – have failed. Only hearing can prove that the truth about this sacrament was revealed in the words of Christ and the saints. The hardest task is to believe them.
