Yāqūt (ruby orhyacinth) was thekunya of Ibn Abdullāh ("son ofAbdullāh"). He was born inConstantinople, the capital of theByzantine Empire, called in Arabical-Rūm, whence hisnisba "al-Rūmi".[2] Captured in war and enslaved,[2] Yāqūt became "mawali"[note 1] to ‘Askar ibn Abī Naṣr al-Ḥamawī, a trader ofBaghdad,Iraq, the seat of theAbbasid Caliphate, from whom he received thelaqab "al-Hamawī". As ‘Askar's apprentice, he learned about accounting and commerce, becoming his envoy on trade missions and travelling twice or three times toKish in thePersian Gulf.[5] In 1194, ‘Askar stopped his salary over some dispute and Yāqūt found work as copyist to support himself. He embarked on a course of study under the grammarianAl-‘Ukbarî. Five years later he was on another mission to Kish for ‘Askar. On his return to Baghdad he set up as a bookseller and began his writing career.[6]
Yāqūt spent ten years travelling in Iran,Syria, and Egypt and his significance as a scholar lies in his testimony of the great, and largely lost, literary heritage found in libraries east of theCaspian Sea, being one of the last visitors before their destruction byMongol invaders. He gained much material from the libraries of theancient cities ofMerv – where he had studied for two years[7] – and ofBalkh. Circa 1222, he was working on his "Geography" inMosul and completed the first draft in 1224. In 1227 he was inAlexandria. From there he moved toAleppo, where he died in 1229.[6]
Kitāb Mu'jam al-Buldān (Arabic:معجم البلدان) "Dictionary of Countries"; Classified a "literary geography", composed between 1224 and 1228, and completed a year before the author's death.
