One of the oldest preserved works of Rovan is the colored plaster cast bust of Arturo Fittke, signed and dated 1896 on the left shoulder.

[1] Among his works from the early 1900s are Il nemico, which won the Rittmeyer Prize in 1905 and was exposed at the Venice Biennale the same year, and La pensosa (1903).

"[2] Among his works from the 1910s are the marbles Il sorriso (1910) and Bust of Alessandro Manussi (1910), and the plaster casts Natura (1910) and La madre (1913).

He also produced the Monument Rossi Tenze de Mayer, whose cast model of the central part, called L'annegato and completed already in 1915, was the only sculpture exhibited at the 1922 Permanente di Trieste.

[2][4] Among his works from the 1920s is the plaster cast bust of his friend Italo Svevo, completed just one year before the demise of the writer, who died on 13 September 1928 in a car crash.

Other members included Umberto Saba, who in 1921 dedicated his Canzoniere to his "six readers" Bazlen, Romanellis, Giotti, Schiffrer, Rovan and Bolaffio.

[5][2] Of this bust was said that it presents the "limpid and blunt line of the mature Rovan, that in this case well interprets the image of the writer, especially in his expression, which is hieratic and realistic.
