This small work is the cycle of Seismic Works. Strong emotions and fear had during the earthquake in May 2012 in Ferrara, are reinterpreted through the houses of the city, their tremor, instability, nothing is more firm. Everything is shaking, trembling and heart beats. I chose to use the old stamps as they are, par excellence, the most "stop" may be, different from calligraphy and the sign, involving more than one intimacy and emotional, personal. It also shakes. The stamp, the stability of the sign, a sign of pre-established and repeatable, is shaken. The earth trembles and shakes the heart Ferrara.
