often depicted as an elderly bishop with the executioner's arm paralyzed until the saint has completed his song. The Roman Martyrology states: “In Pontus, the birthday of Saint Athenogenes, [is celebrated. He was] an aged theologian, who, when about to consummate his martyrdom by fire, sang a hymn of joy, which he left in writing to his disciples.” He is probably identical to the bishop who was martyred with ten disciples in Sebaste, Armenia, on July 16 during the reign of Emperor Diocletian, most probably ca. A.D. 305. Sophronius of Jerusalem (560− 638), who was known for his poetry, is believed to have revised the hymn and Orthodox liturgical books often identify him as the author, e.g., in the Slavonic text below. Modern usage Orthodox Christianity The hymn is a fixed part of the Orthodox vespers service, sung or recited daily, at the entrance when great vespers is celebrated and, in all cases, after the "lamp lighting psalms", aka, "Lord, I have cried..." and their stichera and immediately preceding the prokeimenon. Armenian Rite In the Armenian Rite the hymn is sung only on Saturday evening (i.e., Sunday Eve) and on the eve of certain feast days. The name of the text in Armenian is Loys Zvart. Anglicanism The hymn was translated into English meter by John Keble, one of the leaders of the Oxford Movement within Anglicanism, in 1834, as "Hail, Gladdening Light". Because Keble retained the original irregular metre, it was not suited to any existing hymn tune; however, Sir John Stainer wrote music specifically for it based on Anglican chant. His tune, Sebaste, was first published in 1875 in Hymns Ancient and Modern, while Stainer was organist at St Paul's Cathedral, London. Keble's version was also set as an anthem for eight voices by Charles Wood in 1912. Another translation was made by the 19th-century U.S. poet Henry Wadsworth Longfellow; a third translation, by Robert Bridges, has appeared in several hymnals with music composed by Louis Bourgeois. The traditional Anglican service of Evening Prayer did not call for the use of the hymn, though any of these versifications might be sung at those points in the service which provided for the singing of a hymn or anthem. More recently, some Anglican bodies have adopted it as part of the evening liturgy. For example, the 1979 American Book of Common Prayer prescribes it, in the prose translation given below,
