This text is an attempt to trace up some signs of Jewish and Christian religiosity in the poetry of Aleksander Wat concentrating on mystic structures and emblems deep-rooted in Jewish religious, mystic tradition and also on some Christian motives, for example the figure of Jesus Christ. We deal mainly with the Jewish roots and circumstances of Watʼs poetic and itʼs relationship with sacrum, with a kind of intertextual dialogue with many cultural symbols and concepts associated with Jewish mystique or the Christian tradition.
