Cyrus II (Syriac: Qiyore[1] or Qūrā;[2] died 498) was the archbishop of Edessa and metropolitan of Osrhoene from 471 until his death.
[2] He was opposed to the Antiochene theology of the school of the Persians in Edessa and he successfully appealed to the Emperor Zeno to have it shut down.
Its leading scholars, including Narsai, went into exile in Persia and founded the school of Nisibis.
[2] A church dedicated to the Theotokos was built on the site of the school, according to Simeon of Beth Arsham.
[2][4] In the year 809 of the Seleucid era (either 496 or 497), during an outbreak of the "disease of tumours", Cyrus urged the people to make silver litter for carrying the Eucharistic vessels during the commemorations of martyrs.
