According to Gibb in the introduction (Volume I):
''the Turks very early appropriated the entire Persian literary system down to its minute detail, and that in the same unquestioning and wholehearted fashion in which they had already accepted Islam.''
The Saljuqs had, in the words of the same author:
''Attained a very considerable degree of culture, thanks entirely to Persian tutorage. About the middle of the eleventh century they [that is, the Saljuqs] had overrun Persia, when, as so often happened, the Barbarian conquerors adopted the culture of their civilized subjects. Rapidly the Seljuq Turks pushed their conquest westward, ever carrying with them Persian culture...o, when some hundred and fifty years later Sulayman's son [the leader of the Ottomans]... penetrated into Asia Minor, they [the Ottomans] found that although Seljuq Turkish was the everyday speech of the people, Persian was the language of the court, while Persian literature and Persian culture reigned supreme. It is to the Seljuqs with whom they were thus fused, that the Ottomans, strictly so called, owe their literary education; this therefore was of necessity Persian as the Seljuqs knew no other. The Turks were not content with learning from the Persians how to express thought; they went to them to learn what to think and in what way to think. In practical matters, in the affairs of everyday life and in the business of government, they preferred their own ideas; but in the sphere of science and literature they went to school with the Persian, intent not merely on acquiring his method, but on entering into his spirit, thinking his thought and feeling his feelings. And in this school they continued so long as there was a master to teach them; for the step thus taken at the outset developed into a practice; it became the rule with the Turkish poets to look ever Persia-ward for guidance and to follow whatever fashion might prevail there. Thus it comes about that for centuries Ottoman poetry continued to reflect as in a glass the several phases through which that of Persia passed...o the first Ottoman poets, and their successors through many a generation, strove with all their strength to write what is little else than Persian poetry in Turkish words. But such was not consciously their aim; of national feeling in poetry they dreamed not; poetry was to them one and indivisible, the language in which it was written merely an unimportant accident.''
