The Chronicle of Smbat Sparapet describes an earthquake that produced multiple shocks in the middle of the night. Its sound was a rumble accompanied by terrible roars, and the sea got up, and the mountains and hills made terrifying sounds. A great number of cities were said to have been ruined. Collapsed cities included Antioch, Mecis (Mamistra = Mopsuestia?), Hisn-Mansur, Kaysum, Ablastha, Raban, and Samosata. Marash was said to be completely overturned with forty thousand dead. A church collapse at the Basilian Monastery in the Black Mountains (location debated) caused the deaths of two doctors and thirty monks. The specific date provided in the *Chronicle of Smbat* appears to be in error. The earthquake is said to have struck in the Armenian month of Mareri in the Armenian year 563, which corresponds to a Julian date range of 18 November – 17 December 1114 CE. However, the chronicle also states that the earthquake occurred on the day of the Finding of the Cross, which is typically celebrated on 15 September, or in some traditions on 25 October. Ambraseys (2009) observed that the account in the Chronicle of Sembat ... is based in part on Matthew of Edessa’s record, from which it takes the date of the Finding of the Cross and the Armenian year 563. Thus, like Matthew, Smbat may have referred to the wrong festival. If the intended reference was to the eve of the Feast of Saint Andrew, then the event would date to the night of 29 November 1114 CE, in agreement with other authors.
