The Akathist is also known by the first three words of its prooimion (preamble), Têi hypermáchōi strategôi (Τῇ ὑπερμάχῳ στρατηγῷ, "To you, invincible champion") addressed to Holy Mary (Panagia Theotokos, "The all-holy birth-giver of God").
[1] According to the synaxary the origin of the feast is assigned by the Synaxarion to the year 626, when Constantinople, in the reign of Heraclius, was attacked by the Persians and Avars but saved through the intervention of the Most Holy Theotokos.
"From that time, therefore, the Church, in memory of so great and so divine a miracle, desired this day to be a feast in honour of the Mother of God ... and called it Acathistus" (Synaxarion).
However the feast may have originated, the Synaxarion commemorates two other victories, under Leo III the Isaurian, and Constantine Pogonatus, similarly ascribed to the intervention of the Theotokos.
His position as sacristan would naturally suggest such a tribute to the Theotokos, as the hymn only gives more elaborately the sentiments condensed into two epigrams of Pisida found in her church at Blachernae.
[5][6] Cunningham concurs with Peltomaa's analysis of the hymn's Christology but postulates, from its "highly developed poetic form" and elaborate invocations of Mary, a somewhat later provenance of the latter 5th/early 6th century.
Following Renoux he argues that the hymns, which are colourful and invocatory, contain theology closest to mid-5th century homilists, bearing witness to a highly developed cult of Mary at an earlier period than previous generations of scholars had appreciated.
[10] Since the 14th century the Akathist moved from the menaion to the moveable cycle of the triodion, and the custom established that the whole hymn was sung in four sections throughout Lent.
[13] The hymn itself is divided into thirteen parts, each of which is composed of a kontakion and an oikos (Greek: οίκος, house, possibly derived from Syriac terminology).
The final kontakion is the famous "Tēi Hypermáchōi Stratēgōi" ("Unto the Defender General"), a hymn addressing Mary as the savior of Constantinople in the 626 siege: Another characteristic feature of the Akathist is the extraordinary length of the refrain or ephymnion which consists of a great number of verses beginning with χαῖρε (“Rejoice”) which are called in Greek Chairetismoi (Χαιρετισμοί, "Rejoicings") or in Arabic Madayeh, respectively; in the Slavic tradition these are known as Khayretizmy (Хайретизмы).
Each of the long oikoi include a seven-line stanza followed by six couplets employing rhyme, assonance and alliteration, beginning with the greeting Chaíre and ending with the refrain, "Rejoice, Bride without bridegroom!"
The Enchiridion Indulgentiarum of 2004 confirmed the plenary indulgence on condition that it is recited piously in a church or oratory (even alone), in a family, religious community, an association of Christ's faithful or, more generally, in a meeting of a plurality of people who come together honestly for this purpose.
The inscription on the back of the icon states it was a gift to Saint Dionysius by Emperor Alexios III Komnenos, upon his visit to Trebizond in Asia Minor.
