[1] He was influenced by certain theories of the Italian philosopher Benedetto Croce and the German linguist Karl Vossler.

[3] Bartoli used data gathered in 1897 from the last speaker of Dalmatian, Tuone Udaina, who was killed in an explosives accident on 10 June 1898.

He also wrote Introduzione alla neolinguistica ("Introduction to neolinguistics", 1925) and Saggi di linguistica spaziale ("Essays in spatial linguistics", 1945) and was the teacher of Antonio Gramsci.

Influenced greatly by his mentor Wilhelm Wilhelm Meyer-Lübke and by some of the theories of Benedetto Croce and Karl Vossler, he took a keen interest in Italian dialectology, a then emerging and methodologically advanced discipline, and wrote works on the Dalmatian language, including Das Dalmatische (1906) [5]..
