include, among others: the nightingale (بلبل bülbül) — the rose (ﮔل gül) the world (جهان cihan; عالم ‘âlem) — the rosegarden (ﮔﻠﺴﺘﺎن gülistan; ﮔﻠﺸﻦ gülşen) the ascetic (زاهد zâhid) — the dervish (درويش derviş) As the opposition of "the ascetic" and "the dervish" suggests, Divan poetry—much like Azerbaijani folk poetry—was heavily influenced by Shia Islam. One of the primary characteristics of Divan poetry, however—as of the Persian poetry before it—was its mingling of the mystical Sufi element with a profane and even erotic element. Thus, the pairing of "the nightingale" and "the rose" simultaneously suggests two different relationships: the relationship between the fervent lover ("the nightingale") and the inconstant beloved ("the rose") the relationship between the individual Sufi practitioner (who is often characterized in Sufism as a lover) and God (who is considered the ultimate source and object of love) Similarly, "the world" refers simultaneously to the physical world and to this physical world considered as the abode of sorrow and impermanence, while "the rosegarden" refers simultaneously to a literal garden and to the garden of Paradise. "The nightingale", or suffering lover, is often seen as situated—both literally and figuratively—in "the world", while "the rose", or beloved, is seen as being in "the rose-garden". Ottoman and Safavid divan poetry heavily influenced each other. As for the development of Divan poetry over the more than 500 years of its existence, that is—as the Ottomanist Walter G. Andrews points out—a study still in its infancy; clearly defined movements and periods have not yet been decided upon. Early in the history of the tradition, the Persian influence was very strong, but this was mitigated somewhat through the influence of poets such as the Azerbaijani Nesîmî (1369–1417) and the Uzbek/Uyghur Ali Şîr Nevâî (1441–1501), both of whom offered strong arguments for the poetic status of the Turkic languages as against the much-venerated Persian. Partly as a result of such arguments, Divan poetry in its strongest period—from the 16th to the 18th centuries—came to display a unique balance of Persian and Turkic elements, until the Persian influence began to predominate again in the early 19th century. Azerbaijani poets although they had been inspired and influenced by classical Persian poetry, it would be a superficial judgment to consider the former as blind imitators of the latters, as is often done.
