A journal on spiritual and metaphysical protection, Summa takes its name from a medieval literary genre that aimed to cover the whole terrain of a subject. Each edition of Summa brings together writers, artists and philosophers to contemplate objects of worship and personal significance, apotropaic rituals, and verbal charms, the invisible within the visible, the ineffable within the spoken, and the paradoxical presence of mystery within the rational. Summa is published by Tabayer. Explore Issue>
