John of Ephesus
John of Ephesus (or of Asia) (Greek: Ίωάννης ό Έφέσιος, Classical Syriac: ܝܘܚܢܢ ܕܐܦܣܘܣ, c. 507 – c. 588 AD) was a leader of the early Syriac Orthodox Church in the sixth century and one of the earliest and the most important historians to write in Syriac. John was a bishop, historian, and writer. He provides one of the only first-hand accounts of the Plague of Justinian. He was also alive in what has been called the worst year in history, 536.
