The Chronicle of Seert, sometimes called the Histoire nestorienne, is an ecclesiastical history written in Arabic by an anonymous Nestorian writer, at an unknown date between the ninth and the eleventh century.
[3] The Chronicle deals with ecclesiastical, social, and political issues of the Persian Christian church giving a history of its leaders and notable members.
It details the growth and prospering of the Nestorian Church despite alternating periods of persecution and toleration under the Zoroastrian rulers of Sassanid Persia.
It cannot have been written earlier than the ninth century, as at one point in the text the author quotes the Nestorian patriarch Ishoʿ Bar Nun (823-4).
Some scholars believe that the Chronicle is the work of the ninth-century author Ishoʿdnah of Basra, who is known to have written a three-volume ecclesiastical history.
