Having lived in the early 19th century in Ireland, James Clarence Mangan was an artist and intellectual who received esteemed recognition as Ireland’s national poet. What makes Mangan appealing for the Turkish reader is his amicable interest in the Orient in general, and in the Turkish culture and art in particular. Mangan, who never left Ireland, became acquainted with Ottoman poetry through the German translations of Joseph Freiherr von Hammer-Purgstall. Mangan presented his impressions of Ottoman poetry to English and Irish readers in the six articles entitled “Literae Orientales” he wrote for Dublin University Magazine. In this article, after briefly summarizing the previous studies on Mangan in Turkey, Mangan's six articles on Turkish poetry were examined and Mangan's views were evaluated. It has been concluded that Mangan's positive approach to Turkish literature, encouraging studies on Turkish literature, and conveying the elements of Turkish literature to Western poetry, despite being detached from reality from time to time in his articles, are valuable achievements.
