Ars Judaica is an annual publication of the Department of Jewish Art at Bar-Ilan University. It showcases the Jewish contribution to the visual arts and architecture, from antiquity to the present from a variety of perspectives, including history, iconography, semiotics, psychology, sociology, and folklore. As such, it is a valuable resource for art historians, collectors, curators, and all those interested in the visual arts. In this volume, Annette Weber considers monumental letters and micrography in medieval Ashkenazi bibles, while Batya Brutin contributes 'The Boy from the Warsaw Ghetto as Holocaust Icon in Art.' There are also articles by Moshe Idel on the visualization of colors, looking at David ben Yehudah he-Hasid's Kabbalistic Diagram, and Mathew Baigell on Robert Kirschbaum's art. The volume also includes book reviews. Subject: Art, Art History, Jewish Studies, Religious Studies]
