He then returned to Venice, where he worked till 1796 on 22 of the statues of Prato della Valle in Padua .
For the La Fenice theater (opened in 1792), Ferrari made two statues (Melpomene and Terpsichore) for the facade and helped Giovanni Antonio Moschini complete the bas-reliefs of the interior (only two after the fire of 1837).
Shortly afterwards built the monument to Angelo Emo (now preserved in the church of San Biagio), which many consider his masterpiece.
Late in his career, he began working for the family Savorgnan (Count Giulio was called "my patron" by the sculptor).
His son Gaetano (died 1847) also became a sculptor; he trained with Rinaldo Rinaldi and worked with Canova.
