Da 8 a 9 (2011) embodies the distance between street numbers 8 and 9 in Via Monte Nevoso in Milan: the 8.80 metres  that, in 1978, separated a key hideout of the Red Brigades (the Moro Memoirs were found here) from the home of Fausto Tinelli, the 18-year-old who was killed along with Lorenzo “Iaio” Iannucci for reasons that have never been clarified. In Arena’s work, this distance becomes a thin, suspended bronze body weighing the same as the artist. Transformed into a

universal unit of measure, it unites two places in which events that affected the entire country unfolded and that are still obscure even today.
