Ata-Malik Juvayni
Contary to the early Seljuk rulers, the first Khwarazmshahs were literate. The Khwarazmian grammarian and lexicographer al-Zamakhshari dedicated his Arabic dictionary of "Muqaddimat al-adab" to Atsiz. Ata-Malik Juvayni and Aufi praised Atsiz for his literacy and expertise in writing Persian poetry. Atsiz is often addressed in the panegyric "qasidas" of his poet laureate and chief secretary Rashid al-Din Vatvat (died 1182/3).
