 Denifle and others have proposed that the Latin treatises, which Eckhart prepared for publication very carefully, were essential to a full understanding of Eckhart.In 1923, Eckhart's "Essential Sermons, Commentaries, Treatises and Defense" (also known as the "Rechtsfertigung", or "Vindicatory Document") was re-published.The "Defense" recorded Eckhart's responses against two of the Inquisitional proceedings brought against him at Cologne, and details of the circumstances of Eckhart's trial.
