The writings handed down under the name of Dionigi Aeropagita gave rise to numerous discussions from the Middle Ages onwards. They are mentioned for the first time around 532 by Innocent Bishop of Maronia, but already on the occasion of the great religious conference held in Constantinople (533) doubts began to arise about their authenticity. Introduced in the West by Pope Martin I, they spread rapidly and steadily and throughout the Middle Ages there was no doubt at all of their apocryphal character. Recent studies and research by H. Kock and J. Stiglimayr have shown that the aeropagite studies were composed in Syria around the year 500 and largely derive from the Neoplatonist Procus. Among the numerous Latin translations, one of the most important is certainly this one by Marsilio Ficino.
