Anvari (1126–1189), full name Awhad ad-Din 'Ali ibn Mohammad Khavarani or Awhad ad-Din 'Ali ibn Mahmud (اوحدالدین علی ابن محمد انوری) was a Persian poet. Anvarī was born in Abivard (now in Turkmenistan) and died in Balkh, Khorāsān (now in Afghanistan). He studied science and literature at the collegiate institute in Toon (now Ferdows, Iran), becoming a famous astronomer as well as a poet. Anvari's poems were collected in a Deewan, and contains panegyrics, eulogies, satire, and others. His elegy "Tears of Khorasan", translated into English in 1789, is considered to be one of the most beautiful poems in Persian literature. The Cambridge History of Iran calls Anvari "one of the greatest figures in Persian literature". Despite their beauty, his poems often required much help with interpretation, as they were often complex and difficult to understand. Anvari's panegyric in honour of the Seljuk sultan Sultan Sanjar (1117–1157), ruler of Khorasan, won him royal favour, and allowed him to go on to enjoy the patronage of two of Sanjar's successors. However, when his prophecy of disasters in October 1185 failed, he fell out of favour with the kingship, and was forced into a life of scholarly service, eventually taking his own life in 1189. Anwari was born in the Khawaran district (Balkh) of Khorasan early in the 12th century. He enjoyed the special favour of the Sultan Sanjar, whom he attended in all his warlike expeditions. On one occasion, when the sultan was besieging the fortress of Hazarasp, a fierce poetical conflict was maintained between Anwari and his rival Rashidi, who was within the beleaguered castle, by means of verses fastened to arrows. His literary powers are considerable, as shown in his famous lament over the ruin caused by the Ghuzz tribesmen in Khurasan, and his exercises in irony and ridicule make pungent reading. He was adept in astrology and considered himself to be superior to his contemporaries in logic, music, theology, mathematics and all other intellectual pursuits.
