Kanones on saints according to the eight modes

"Joseph the Hymnographer (c. AD 816-886) belonged to the Constantinopolitan intellectual élite and was a prominent teacher. His liturgical poetic oeuvre comprises different subgenres. However, he is best known for his kanones. A kanon is a long hymn penned in one of the eight Byzantine modes and sung during the early morning office (Orthros). The present critical edition aims to determine the original text of groups consisting of eight kanones each and dedicated to prominent saints [Saint Thomas, Saint Demetrius, Saint Michael Archangel, Saint Stephen, Saint John Chrysostom, Forty Martys of Sebaste, Saint Christopher, Saint Panteleon]. Within each group, Joseph composed one kanon per mode."--
