RT Article T1 Un canon inédit de Nicétas Stéthatos en l'honneur de saint Théodore Stoudite JF Analecta Bollandiana VO 137 IS 1 SP 103 OP 119 A1 Kaklamanos, Dimosthenis 1979- LA French PB MetaPress YR 2019 UL https://ixtheo.de/Record/1671848705 AB Codex no. 184 from the Library of the Patriarchate of Alexandria constitutes the only known witness of an acolouthia for St Theodore the Studite (759-826). This article includes a critical edition of the above mentioned acolouthia. At the same time, the issue of St Theodore's veneration is briefly examined as well its relevant hymnographical tradition focusing especially on the original authorship of the Canon included in the acolouthia. We attribute this Canon to the prominent Byzantine theologian, Niketas Stethatos, based on a significant personal piece of information relating to its work that he includes in St Symeon's the New Theologian Vita, as well as to the presence of rare words and expressions that are also found in both this Canon under publication and in other works of Niketas Stethatos.
