It may appear that the sea (open, deep and endless) and poem (concentrated and delimited), an elementary protean force and, to some extent, a solid form respectively, are in contradiction. Nevertheless both are defined by a horizontal and vertical dimension. The sea’s characteristic motion is that of swinging, while a poem is defined by its rhythm. This paper will focus on authors who were occupied with the sea in their poetry, essays or prose, or depicted a picture of the sea in the fine arts. The aim of this paper is to explore the representation of the sea regarding the nature of the text or medium and consequently to uncover the specifics of poems about the sea.
