One of the aspects not well studied yet is about relationships between architects and painters at the end of
XIXth and beginning XXth centuries. In this particular case the author analyzes friendship between Giuseppe
Barison (1853-1931) and Enrico Nordio (1851-1923). The two friends were very soon in contact for their training
in Karl Emil Haase atelier in Trieste and then in Vienna, Nordio becoming an important architect, Barison
one of the most relevant painter at the time. Nordio collected many Barison’s paintings as well as Giacomo
Zammattio (1855-1927), another important architect between Trieste and Rijeka who was also friend and
collegue of Barison in Vienna at the Academy of Fine Arts.
