Smbat Sparapet's Chronicle is a major source for the history of the Armenian Kingdom of Cilicia. Roughly three-quarters of the work consists of a summary of Matthew of Edessa's Chronicle which describes the period from 951 to 1136 and its continuation by Gregory the Priest, covering the period from 1136-1162. Given that Matthew's work has survived, by far the most important part of Smbat Sparapet's Chronicle is its original contribution, devoted to the period from 1163 to 1272. Volume II covers the period from 1151 to 1272.
