西班牙著名诗人路易斯·德·贡戈拉于17世纪初创作的长诗《孤独》不仅代表其诗风的激进突转，也代表巴洛克诗歌攀上新的高峰。借助法国后结构主义批评家朱丽娅·克里斯蒂娃提出的“互文性”概念，从多重角度对文本进行分析，作为互文主体的《孤独》是非文本因素与文本因素交互影响的产物。巴洛克本体论危机下的贡戈拉融合西班牙哈布斯堡王朝宫廷风尚与其他非文本因素，将神话史诗、维吉尔《牧歌》、文艺复兴诗歌经典等文本转化吸收，从而促成了《孤独》的问世，并对后世西语文学乃至世界文学的发展产生了深远影响。

The long poem Soledades written by the famous Spanish poet Luis de Góngora in the early 17th century not only represents a radical change in his poetic style, but also represents a new peak of Baroque poetry. Based on the concept of Intertextuality proposed by French post-structuralism critic Julia Kristeva, this paper analyzes the text from multiple perspectives, and Soledades, as the subject of intersexuality, is influenced by non-textual factors and textual factors. Against the background of the ontological crisis, Góngora integrated Habsburg court customs and other non-textual factors, and absorbed texts such as myths, epics, Virgil’s Eclogue and Renaissance poetry classics，which contributed to the Soledades and had a profound impact on the development of Spanish literature and even the literature of the whole world.
