Joseph of the Studium

Joseph of the Studium [Joseph of Thessalonica]. This person not the same person wrongly named by Dr. Neale in his Hymns of the Eastern Church as Joseph of the Studium, author of the great Canon for the Ascension. That Joseph is St. Joseph the Hymnographer. Joseph of Thessalonica, younger brother of St. Theodore of the Studium, q.v., was some time Bishop of Thessalonica, and died in prison, after great suffering inflicted by command of Theophilus. He was probably the author of the Triodia in the Triodion, and certainly of five Canons in the Pentecostarion to which his name is prefixed. His pieces have not been translated into English. [Rev. H. Leigh Bennett, M.A.]
