Al-Asmaʿi, or Asmai; an early philologist and one of three leading Arabic grammarians of the Basra school. Celebrated at the court of the Abbasid caliph, Hārūn al-Rashīd, as polymath and prolific author on philology, poetry, genealogy, and natural science, he pioneered zoology studies in animal-human anatomical science. He compiled an important poetry anthology, the Asma'iyyat, and was credited with composing an epic on the life of Antarah ibn Shaddad. A protégé of Al-Khalil ibn Ahmad al-Farahidi and Abu 'Amr ibn al-'Ala', he was a contemporary and rival of Abū ʿUbaidah and Sibawayhi also of the Basran school.
