Dionysius was born in
Tal Mahre, near the city of
Raqqa, into a wealthy family from
Edessa, and became a monk at the Monastery of
Qenneshre, where he studied philology, jurisprudence, philosophy, and theology. In 818, Dionysius was elected Patriarch of Antioch unanimously by a synod of forty-eight bishops. After his consecration, he issued a proclamation and held three councils in Raqqa in the same year, at which he issued twelve canons. In 826, Dionysius visited Egypt in the company of the
Abbasid general
Abdallah ibn Tahir al-Khurasani. He later held a council at the Monastery of Euspholis in 828, and returned to Egypt in 832 in the company of
Caliph Al-Ma'mun. Whilst in Egypt, Dionysius met with
Pope Jacob of Alexandria, head of the
Coptic Orthodox Church, a fellow
miaphysite church, and several Coptic Orthodox bishops outside of the city of Tannis. He held another council at the city of
Tagrit in 834, and met with Al-Ma'mun in
Baghdad, and also his successor, Caliph
Al-Mu'tasim. A total of one hundred bishops were ordained by Dionysius during his tenure and he served as patriarch until his death on 22 August 845. ==Works==
