Leszek Berezowski is behind us, but let&#8217;s return for a moment to the event itself. During yesterday&#8217;s lecture, over 220 high school students gathered in Aula Leopoldy\u0144ska, who came not only from secondary schools in Wroc\u0142aw, but also from Wa\u0142brzych, Namys\u0142\u00f3w and Jarocin. The introductory speech was delivered by prof. Robert Olkiewicz, who introduced young people to the topic of the upcoming holidays. During the lecture, prof. Leszek Berezowski talked about the history of Saint Nicholas, his origins and activities, ancient customs, traditions and beliefs, as well as how the figure of Saint Nicholas has changed over the centuries.<\/p>\n<\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">We would like to remind you that the online lecture by prof. Leszek Berezowski is available for another week <a href=\"https:\/\/www.youtube.com\/watch?v=H_phvOWAc0I\">on the IFA UWr YouTube channel.<\/a><\/p>\n\n\n<div class=\"bs_gallery\"
