The Book of Odes (), also known as the Biblical Odes, refers to a collection of hymns and prayers referencing the Bible and used as a part of liturgies in some denominations. Collections of odes can be found in every language of Christian literature from antiquity through the Middle Ages, especially in Greek, Latin, Coptic, Syriac, Arabic, Ethiopic, Armenian, Georgian, and Slavonic, and although there were some consistent selections, the extent of the list often varied. They are often circulated with or interwoven with the Psalms, although sometimes they were circulated as independent books. The biblical odes form the basis for the Eastern Orthodox canon sung during matins and other services.
The Odes were thought to have existed independently prior to being compiled into a list. Hippolytus of Rome wrote homilies on the Song of the Three Holy Children and the Song of Moses in the early third century. By the 4th century, Eusebius reported that many hymns and songs had been written. The earliest surviving collection is found in the fifth century Codex Alexandrinus, which contains 14 odes appended after the Psalms. By the 6th century, the list was predominantly circulating as a collection of the first nine.
The original collection of Odes was compiled early in the Roman imperial era and consisted of Old Testament songs and prayers found in prose contexts. The earliest collections can be found ranging from nine to sixteen text collections, although these. The critical Greek edition produced by Alfred Rahlfs presents the nine-ode Byzantine Greek sequence before the other Greek Odes, as well as including the Song of the Vineyard (Isaiah 5:1-9) as Ode 10 despite its absence in Codex Alexandrinus.
The listing of Odes as presented by Rahlfs are:
