Book excerpt: Kata ton daimona eaytoy (κατά ton δαίμονα εαυτού) is a phrase from the ancient Greek, a concept embraced by the stoicism that can be interpreted in many ways in the modern day. This philosophy is best perceived in the culture of Fin de siècle, which lasted from 1880s till around 1890s. It was considered a period of degeneration but also a period for a new beginning. The transition between a fact and the destruction of it to create a new reality. The term Fin de siècle is commonly applied to the French artists, but it also represents globally the "end of an era" and the beginning of a new one. Castano's dark poetry aims to achieve this concept, showing that even beauty has a dark side, in a hopeful attempt to make us appreciate it even more. When we know the whole of our reality, we know better what we have.
