The cultural association TRAleVOLTE presents La forma dell'acqua, which takes place as part of Rome's fourth edition of the Giornata del Contemporaneo initiative. The exhibition is centred around Silvia Stucky's tsukubai – a traditional Japanese water container carved from stone – which goes on permanent display in a corner of the Passionist gardens at the Scala Santa. In the traditions of the Far East, stone and water are viewed as opposite but complementary elements of nature, and the tsukubai, with its purifying function through the washing of hands, creates a link with the holy water present in the Scala Santa church. Curated by Francesco Pezzini and Alessandra Scerrato, the event at the neighbouring TRAleVOLTE also includes an exhibition of photographs taken in Japan by Stucky, with images ranging from tsukubai to the gardens of Kyoto and Nara, as well as a work by Rome-based Japanese sculptor Nobushige Akiyama.
