Eastern literature in the middle ages

Abū Ḥāmid bin Abū Bakr Ibrāhīm (c. 1145 – c. 1221), better known by his pen-names Farīd ud-Dīn and ʿAṭṭār of Nishapur (Attar means apothecary), was an Iranian poet, theoretician of Sufism, and hagiographer from Nishapur who had an immense and lasting influence on Persian poetry and Sufism. He wrote a collection of lyrical poems and number of long poems in the philosophical tradition of Islamic mysticism, as well as a prose work with biographies and sayings of famous Muslim mystics. The Conference of the Birds, The Book of Divine, and Memorial of the Saints are among his best known works.
Biography
Information about Attar's life is scarce and has been mythologised over the centuries. However, Attar was born to a Persian family and he practised the profession of pharmacist and personally attended to a very large number of customers. He is mentioned by only two of his contemporaries, `Awfi and Tusi. However, all sources confirm that he was from Nishapur, a major city of medieval Khorasan (now located in the northeast of Iran), and according to `Awfi, he was a poet of the Seljuq period.
Attar was probably the son of a prosperous chemist, receiving an excellent education in various fields. While his works say little else about his life, they tell us that he practised the profession of pharmacy and personally attended to a very large number of customers. The people he helped in the pharmacy used to confide their troubles in Attar and this affected him deeply. Eventually, he abandoned his pharmacy store and travelled widely - to Baghdad, Basra, Kufa, Mecca, Medina, Damascus, Khwarizm, Turkistan, and India, meeting with Sufi Shaykhs - and returned promoting Sufi ideas. Attar was a Sunni Muslim.
From childhood onward Attar, encouraged by his father, was interested in the Sufis and their sayings and way of life, and regarded their saints as his spiritual guides. At the age of 78, Attar died a violent death in the massacre which the Mongols inflicted on Nishapur in April 1221. Today, his mausoleum is located in Nishapur. It was built by Ali-Shir Nava'i in the 16th century and later on underwent a total renovation during the rule of Reza Shah in 1940.
The thoughts depicted in Attar's works reflects the whole evolution of the Sufi movement. The starting point is the idea that the body-bound soul's awaited release and return to its source in the other world can be experienced during the present life in mystic union attainable through inward purification. In explaining his thoughts, 'Attar uses material not only from specifically Sufi sources but also from older ascetic legacies. Although his heroes are for the most part Sufis and ascetics, he also introduces stories from historical chronicles, collections of anecdotes, and all types of high-esteemed literature. His talent for perception of deeper meanings behind outward appearances enables him to turn details of everyday life into illustrations of his thoughts. The idiosyncrasy of Attar's presentations invalidates his works as sources for study of the historical persons whom he introduces. As sources on the hagiology and phenomenology of Sufism, however, his works have immense value.
Judging from Attar's writings, he approached the available Aristotelian heritage with scepticism and dislike. He did not seem to want to reveal the secrets of nature. This is particularly remarkable in the case of medicine, which fell well within the scope of his professional expertise as pharmacist. He obviously had no motive for sharing his expert knowledge in the manner customary among court panegyrists, whose type of poetry he despised and never practised. Such knowledge is only brought into his works in contexts where the theme of a story touches on a branch of the natural sciences.
Poetry
Attar's most famous poem by far is his Conference of the Birds (Mantiq al-tayr). Like many of his other poems, it is in the mathnawi genre of rhyming couplets. While the mathnawi genre of poetry may use a variety of different metres, Attar adopted a particular meter, that was later imitated by Rumi in his famous Mathnawi-yi Ma’nawi, which then became the mathnawi metre par excellence. The first recorded use of this metre for a mathnawi poem took place at the Nizari Ismaili fortress of Girdkuh between 1131 and 1139. It likely set the stage for later poetry in this style by mystics such as Attar and Rumi.
In the introductions of Mukhtār-Nāma and Khusraw-Nāma, Attar lists the titles of further products of his pen:
Manṭiq-uṭ-Ṭayr
Dīwān
Asrār-Nāma
Manṭiq-uṭ-Ṭayr, also known as Maqāmāt-uṭ-Ṭuyūr
Muṣībat-Nāma
Ilāhī-Nāma
Jawāhir-Nāma
Šarḥ al-Qalb[18]
He also states, in the introduction of the Mukhtār-Nāma, that he destroyed the Jawāhir-Nāma' and the Šarḥ al-Qalb with his own hand.

Although the contemporary sources confirm only Attar's authorship of the Dīwān and the Manṭiq-uṭ-Ṭayr, there are no grounds for doubting the authenticity of the Mukhtār-Nāma and Khusraw-Nāma and their prefaces. One work is missing from these lists, namely the Tadhkirat-ul-Awliyā, which was probably omitted because it is a prose work; its attribution to Attar is scarcely open to question. In its introduction Attar mentions three other works of his, including one entitled Šarḥ al-Qalb, presumably the same that he destroyed. The nature of the other two, entitled Kašf al-Asrār and Maʿrifat al-Nafs , remains unknown.
