 In 1960, however, a manuscript ("in agro dominico") was discovered containing six hundred excerpts from Eckhart, clearly deriving from an original made in the Cologne Dominican convent "after" the promulgation of the bull condemning Eckhart's writings, as notations from the bull are inserted into the manuscript.The manuscript came into the possession of the Carthusians in Basel, demonstrating that some Dominicans and Carthusians had continued to read Eckhart's work.It is also clear that Nicholas of Cusa, Archbishop of Cologne in the 1430s and 1440s, engaged in extensive study of Eckhart.
