Картина: Собор Святої Софії в Царгороді (Константинополі) у 12 столітті. Співає хор "Видубичі". Сугуба (посилена) єктенія починається словами: «Помилуй нас, Боже, з великої милості Твоєї, молимося Тобі, вислухай і помилуй». На кожне прохання сугубої єктенії хор відповідає триразовим: «Господи, помилуй!» Тому сама єктенія називається сугубою, або посиленою. Rare painting: Divine service at the Church of Hagia Sophia (Constantinople / Istanbul) in the 12th century. Painting depicts Hagia Sophia, in the twelfth century, during an Orthodox Liturgy, purportedly during a visit by King Richard the I, Coeur de Lion (the Lionhearted). This is a rare glimpse of this Mother Church of Christianity, which was completed in the early sixth century (537) on the site of two earlier Churches dedicated to Holy Wisdom. It was the largest Church in Christendom for nearly a thousand years. After the fall of Constantinople, Turks turned it into mosque. Litany of Fervent Supplication in Ukrainian - Eastern Orthodox chant by Vudubychi choir (Ukrainian Orthodox Church of Kyiv Patriarchate) from Kyiv, Ukraine. Litany of Fervent Supplication, also sometimes Impetratory Litany, Augmented Litany, Fervent Litany—this litany is remarkable because of its fervency (its fervid fervidity), indicated by the threefold response of the choir, "Lord, have mercy" (thrice). At the Divine Liturgy, this litany may also be augmented with special petitions, according to need as the pastor sees fit.
