Ars Judaica is an annual publication of the Department of Jewish Art at Bar-Ilan University. The book 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.
