Abà « YaÿlàḤamzah ibn al-Asad ibn al-QalÃÂnisë (; c. 1071 â 18 March 1160) was an Arab politician and chronicler in 12th-century Damascus.
Hamza, whose kunya was Abà « Yaÿlàand nisba was al-QalÃÂnisë 'the Hatter', descended from the Banu Tamim, and was among the well-educated nobility of the city of Damascus. He studied literature, theology, and fiqh and served firstly as a secretary in, and later the head of, the Chancery of Damascus. He served twice as raþës of the city, an office equivalent to mayor.
His chronicle, the Dhail Taürëkh Dimashq or Mudhayyal Taürëkh Dimashq 'Continuation of the Chronicle of Damascus' was an extension of the chronicle of Hilal al-Sabi', covering the years 1056 to al-Qalanisi's death in 1160. This chronicle is one of the few contemporary accounts of the First Crusade and its immediate aftermath from the Muslim perspective, making it not only a valuable source for modern historians, but also for later 12th-century chronicles, including ibn al-Athir. He also witnessed the siege of Damascus in 1148 during theàSecond Crusade, which ended in a decisive crusader defeat.
The entire material of his chronicle covers the time span of two generations, his father's and his own, al-Qalanisi having experienced the First Crusade at a mature age, although apparently not as a fighter. Analysing the text, H. A. R. Gibb, his first English translator, reaches the conclusion that al-Qalanisi has extracted his information both from eyewitnesses and documents, a fact strengthened by al-Qalanisi's own description of his modus operandi. As a result of al-Qalanisi's careful work, a chief quality noted by Gibb is the accuracy of the chronology of events, for which he even offers the day of the week. Gibb extracted from the chronicle and translated into English the material covering the period 1097âÂÂ1159, which he published in 1932.
