A visionary poet expresses the inner visions of the unknown, which means to see oneself and the world in a different way. However, to be able to express such visions, Arthur Rimbaud and Dino Campana had to create a new or different poetic language that would be capable of expressing such visions. In Rimbauds Illuminations, were I analysed the songs Being Beauteous, Villes and Génie, the poet mainly made use of composing syntagmas which suggest the oniric nature of his visions and are not in accordance with the logic and material reality. In addition, another of Rimbauds caractheristics are the accumulation of nominal phrases, without any articulation of superiority or subordination between them, and different forms of phonetic repetitions. Dino Campana in his Orphic songs, where I analysed the songs La Notte, La Chimera and Genova, also makes use of the nominal style and the creation of syntagmas, which would enhance the oniric and visionary signs of his poems. We also need to add various forms of repetitions, which are almost the poets trademark, and make the exemplification of images almost impossible.
