My first stop was just a few blocks from my apartment, on the banks of the Vistula. The sun was bright and children were soaking up the last days of summer, splashing themselves in the fountain at the base of the Syrene of Warsaw, the mythical symbol of that grand city's defiance, who rears up on bronze waves on her Piscene tail, holding her sword aloft. A mermaid as a symbol of a city? I thought about the value of hybrids, what it means to be part human and animal, how hybrid forms are for non-conformists, for breaking norms that we've outgrown. And most of all, the siren must be heard.
