"Allegoria della Primavera Valenciana" Poliniza Urban Art Festival at the Polytechnic University of Valencia The wall is an allegory of the incidents we had last year in Valencia during the riots between students and police that mass media and political called "Primavera Valenciana" (Spring Valencia). The use of the stain glass on the dark wall to give a sense of light but also fragility, mixing concepts of the police charges, arrests and the arrival of spring inspired in the work of Boticcelli "La Primavera".
