Badi' al-Zamān al-Hamadāni, alternately spelled Badi' uz Zaman (a transliteration which better reflects the pronunciation). (In Persian: بديع الزمان همدانی; CE 969 - 1007 CE) was a medieval Persian man of letters born in Hamadan, Iran. He is best known for his work the Maqamat, a collection of 52 episodic stories of a rogue, Abu al-Fath al-Iskandari, as recounted by a narrator, 'Isa b. Hisham. His Arabic name translates into "The Wonder of the Age".
His letters were first published at Constantinople (1881), and with commentary at Beirut (1890); his maqamas at Constantinople, and with commentary at Beirut (1889). A good idea of the latter may be obtained from Silvestre de Sacys edition of six of the maqamas with French translation and notes in his Chrestomathie arabe, vol. iii. (2nd ed., Paris, 1827). A specimen of the letters is translated into German in A. von Kremers Culturgeschichte des Orients, ii. 470 sqq.
