Dionysius I Telmaharoyo

Dionysius I Telmaharoyo (Latin: Dionysius Telmaharensis) was the Patriarch of Antioch, and head of the Syriac Orthodox Church from 818 until his death in 845. He was also the author of the Annals, an important world history, now lost, which was used as a source by the twelfth-century Jacobite historian Michael the Syrian. Dionysius was credited by Joseph Simon Assemani with the authorship of the Zuqnin Chronicle, an anonymous eighth-century Syriac history, but this attribution is now known to have been mistaken.
