Libellus de expugnatione Terrae Sanctae per Saladinum
The Libellus de expugnatione Terrae Sanctae per Saladinum (Latin for "Little Book about the Conquest of the Holy Land by Saladin"), also called the Chronicon Terrae Sanctae ("Chronicle of the Holy Land"), is a short anonymous Latin account of the conquests of Saladin (Ṣalāḥ al-Dīn) in the Holy Land between 1186 and 1191. The core of the text was written shortly after the events it describes and then supplemented by the addition of an account of the Third Crusade early in the thirteenth century.
