Constantine Manasses (Greek: Κωνσταντῖνος Μανασσῆς; c. 1130 – c. 1187) was a Byzantine chronicler who flourished in the 12th century during the reign of Manuel I Komnenos (1143–1180).
He was the author of a Synopsis Chronike (Σύνοψις Χρονική, "summary chronicle"), which narrates history from the creation of the world to the end of the reign of Nikephoros III Botaneiates (1081), sponsored by Irene Komnene, the emperor's sister-in-law.
[2][3] This translation, which includes several miniatures, was commissioned by tsar Ivan Alexander between 1340 and 1345.
[5] Manasses also wrote the poetical romance Loves of Aristander and Callithea, also in political verse.
Manasses also wrote a short biography of Oppian, and some descriptive pieces (all except one unpublished) on artistic and other subjects.
