Dionysius the Areopagite (Greek Διονύσιος ὁ Ἀρεοπαγίτης) was the judge of the Areopagus who, as related in the Acts of the Apostles, (Acts 17:34), was converted to Christianity by the preaching of the Apostle Paul. According to Dionysius of Corinth, quoted by Eusebius, this Dionysius then became a bishop of Athens
In the early 6th century, a series of famous writings of a mystical nature, employing Neoplatonic language to elucidate Christian theological and mystical ideas, was ascribed to the Areopagite. They have long been recognized as pseudepigrapha and are now attributed to "PseudoDionysius- the Areopagite".
Dionysius was also popularly mis-identified with the martyr of Gaul, Dionysius, the first Bishop of Paris, Saint Denis.
