In this way Pessoa describes the human condition and, on the base of this thought he pursues hi artistic production. The Portuguese poet, born in Lisbon in 1888, created, indeed, a lot of "ETERONIMI", that is a showing of own different personalities, to which he gave an indipendent life and exactly stylistic and ideological features. It means that his "self" was anxious and complex, always searching own truth, a truth expressed also into the Romantic philosophy and Symbolism's study.

So every "Eteronimo" pursues own thematics with a peculiar style. Consequently Pessoa's themas and his literary examples are various: we can find the omosexual engineer who writes lines inspired by Marinetti and Whitman, the neoclassic poet near to Orazio and to the epicurean philosophy, the countryman who expresses his materialist nature destroying formal conventions; the introspective and scettic accountant; the surrealistic writer and finally, of course, Pessoa who signs with his name short poems.

Although Pessoa thinks that he always has to use "eteronimi", he tries equally to find an agreement between these personalities through the music.

The way to conceive himself and the splitting of own personality into "eteronimi" brings the Portuguese poet near to the contemporary Pirandello, an Italian writer, who perceives equally the fragmentary self as a consequence of the restless historical background at the beginning of the 20^th century. His good knowledge of English language, thanks some time spent in South Africa during his youth, took him to write novel in English. Some critics say that his Portuguese style his unequalled because he conceived his works in English. After the time spent in South Africa he remained in his city, Lisbon, linked to its culture and history.
