Literature from the Canary Islands has suffered, in general, complete abandonment and neglect on the part of the critics. It is not until the eighties that a small group of scholars begins to study and defend the importance of the surrealist poetic group or generación de 1930 in the Canary literature of their time. The sea, as a vital topic, takes form and strength in the poetic works of many writers during the modernist and postmodernist movements, and the first vanguards that emerged in the twenties. Among these authors, Pedro García Cabrera and Tomás Morales arose as the most relevant and prolific. Both poets had the opportunities and talent that allowed them to build on the artistic achievements of important peninsular writers at the end of the 19th century and the beginning of the 20th century. Morales and García Cabrera constructed a powerful, personal vision of an insular identity. In their works, the sea, like a double-edged sword, transforms all at once into both a geographical limit and a borderless space. Here the Canario poet can submerge himself to establish a new history and tradition to fill the forgotten literary spaces of Canario insularity. The focus for this dissertation will be the present relationship between the work of these two Canary Island poets and the marine symbolism as a topic to define and enunciate insular identity. Through their works, Canario writers struggle to satisfy their desire to clarify that slippery concept of «canariedad» (or Canary Islands identity) as an insular conscience trapped in a double frame, both historic and geographic.
