Professor Andrew Louth 
Denys the Areopagite [PDF ebook] 

Andrew Louth examines all the traditions on which Denys” work draws: the Fourth Century Greek theologians, pagan philosophy and Syrian Christian thought. The corpus of Denys the Areopagite appeared in the sixth century and have since been deeply influential on Christian thinking both in East and West. Who their author was remains a mystery but in this book Professor Louth documents and comments on his compelling vision of the beauty of God”s world and his revelation, together with his profound awareness of the ultimate mystery of the unknowable God who utterly transcends all being.
