“The articles in A Companion to John of Ruusbroec are solid, lucid, and rooted in Ruusbroec’s writings and the relevant secondary literature. They address satisfactorily the central questions associated with his life, mysticism, manuscript tradition, influence, and historiography. Moreover, enhancing and providing further clarification … are numerous maps and illustrations (several of which are in color), including maps of fourteenth-century Brussels and Ruusbroec’s world in the Brabant, and images of manuscript versions of his works as well as printed editions. Indeed, the Companion is a superlative collection of articles and could certainly now be considered the starting point for native English speakers – and really anyone – interested in John of Ruusbroec.”Andrew J.G. Drenas, University of Massachusetts-Lowell. In: Sixteenth Century Journal, Vol. 45, No. 1 (2015), pp. 148-150.“the present volume is a welcome contribution to the work of this important late medieval mystic.”John T. Slotemaker, Fairfield University. In: Religious Studies Review, Vol. 42, No. 4 (December 2016), p. 302.
