Farid al-Din 'Attar (d. 1221) was the principal Muslim religious poet of the second half of the twelfth century. Best known for his masterpiece "Mantiq al-tayr", or "The Conference of Birds", his verse is still considered to be the finest example of Sufi love poetry in the Persian language after that of Rumi. Distinguished by their provocative and radical theology of love, many lines of 'Attar's epics and lyrics are cited independently of their poems as maxims in their own right. These pithy, paradoxical statements are still known by heart and sung by minstrels throughout Iran, Afghanistan, Tajikistan, and wherever Persian is spoken or understood, such as in the lands of the Indo-Pakistani Subcontinent. Designed to take its place alongside "The Ocean of the Soul", the classic study of 'Attar by Hellmut Ritter, this volume offers the most comprehensive survey of 'Attar's literary works to date, and situates his poetry and prose within the wider context of the Persian Sufi tradition.
