Summary The thematic frame of this issue is the anthropological notion of liminality, applied both to physical as well as imaginary places of transition in medieval art. The volume is thus dedicated to the phenomenon of the limen, the threshold in medieval culture, understood mainly as a spatial, ritual and temporal category. The structure of the book follows the virtual path of any medieval visitor entering the sacred space. While doing so, the visitor encountered and eventually crossed several "liminal zones" that have been constructed around a series of physical and mental thresholds. In order to truly access the sacred - once again both physically and metaphorically - many transitional (micro)rituals were required and were therefore given particular attention within this volume. The volume was published as proceedings of the Liminality and Medieval Art II conference, which was held in October 2018 at the Masaryk University in Brno. Authors were supposed to conceive their contributions in pairs in order to reflect on the selected topics with an interdisciplinary approach. In the end, the very same pattern was also maintained for the final publication. TABLE OF CONTENTS Introduction Kl ra Dole?alov & Ivan Foletti Liminality and Medieval Art.
