The historian Zdenko Zlatar argues that Njegoš's mentor (and later secretary) Sima Milutinović influenced him more than any other person, noting that while Milutinović "was not a great poet or playwright [...] no one in Cetinje or for that matter the whole of Montenegro had a better knowledge of the wider world." Indeed, Milutinović introduced Njegoš to his own poetry, which Professor Svetlana Slapšak describes as being "written in unusual syntax, with unparalleled neologisms and fantastic etymologies". The position of Njegoš's secretary was later occupied by Dimitrije Milaković, a physically disabled Dubrovnik-born polyglot who had studied philosophy in Vienna and came to Montenegro with Vukotić and Vučićević in 1832. Milaković operated the printing press at Cetinje Monastery, served as editor-in-chief of "Grlica" and edited all Njegoš's works prior to their publication. Njegoš was also a great admirer of the Serbian revolutionary Karađorđe, who led the First Serbian Uprising, and dedicated "Gorski vijenac" to his memory. The linguist Vuk Karadžić influenced Njegoš through his reforms of the Serbian language, and used his own fame to popularize Njegoš's work. Moreover, he introduced Njegoš to his inner circle, which included some of the leading Serb poets of the day, such as Branko Radičević and Milica Stojadinović-Srpkinja. Njegoš was also impacted by the works of foreign writers, such as Dante Alighieri's "Divine Comedy" and John Milton's "Paradise Lost"; their influence can be strongly felt in "Luča mikrokozma".
