influenced by De Saussure,in wich way and in wich of his ideas?
(qust. only for the theoricians of literature, I don't accept generalized, "wikipedia" answers)

Answer 1

Barthes was highly influenced by Ferdinand de Saussure's semiology - the formal study of signs and signification.
There are two divergent traditions in semiotics stemming respectively from Saussure and Charles Sanders Peirce. The work of Louis Hjelmslev, Roland Barthes, Claude Lévi-Strauss, Julia Kristeva, Christian Metz and Jean Baudrillard (b 1929) follows in the 'semiological' tradition of Saussure whilst that of Charles W Morris, Ivor A Richards (1893-1979), Charles K Ogden (1989-1957) and Thomas Sebeok (b 1920) is in the 'semiotic' tradition of Peirce. The leading semiotician bridging these two traditions is the celebrated Italian author Umberto Eco, who as the author of the bestseller The Name of the Rose (novel 1980, film 1986) is probably the only semiotician whose film rights are of any value (Eco 1980).
Further developing Saussure's conception of the arbitrariness of speech-sounds in relation to their meaning, Barthes examined the arbitrariness of the linguistic forms more generally and in his 1964 The Eiffel Tower and Other Mythologies he applied the same approach to the hidden assumptions behind popular culture.
But In Elements of Semiology, Barthes proposed the inversion of Saussure's thesis that the study of language would be a part of a larger science of semiology, asserting instead that “it is semiology which is a part of linguistics”. At the same time he analysed literature as a sequence of signs, the meaning of which bears no relation to the intention of the author, but rather is a free construction of the reader.
Barthes's ideas and his approach to writing evolved over the course of his career, and critics often discuss his works in terms of four stages in his critical thinking. In the first stage of his career, which includes such works as Writing Degree Zero, Michelet (1954; Michelet), and Mythologies, Barthes, influenced by the ideas of Sartre and Karl Marx, demonstrates a strong interest in issues of language, its relationship to historical and social context, and its relationship to power. In these works he developed his notion of écriture, the aspect of discourse in which the author's social and historical context imbues his or her writings with unintended meanings that are revealed in structural analysis. In Mythologies Barthes analyzed aspects of contemporary French culture—for example, advertising, travel guides, and professional wrestling—to explore ways in which they support a bourgeois worldview. The next phase of Barthes's career, which also marked the high point of Structuralism in France, is a rigorously theoretical one and includes his famous 1964 essay “Eléments de sémiologie” (published in English as Elements of Semiology). Encompassing the ideas of Saussure, Roman Jakobson, and other noted linguists, Barthes theorized about the role of language versus that of speech. To Barthes, language is based on an abstract set of rules and conventions regulating verbal and written communication, whereas speech refers to individual instances of how that language is used. The third phase of Barthes's career, influenced by French theorists Jacques Derrida and Julia Kristeva, marks a shift in his thinking from Structuralism to Post-Structuralism in the 1970s.
However, his expansive interpretations of Saussure's theories, and his application of those theories to non-linguistic fields of study, led to theoretical difficulties and proclamations of the end of structuralism in those disciplines.

Answer 2

i believe his principles and methods of structuralism were adopted by Barthes
