Pisani's ancestors of French-Italian origin settled at the Levant at the end of the 18th century.
Pisani was therefore fluent in French and Italian and also had some knowledge of Serbo-Croatian.
He was a close friend of Monseigneur Maurice Le Sage d'Hauteroche d'Hulst, founder of the Institut Catholique, and was his secretary from 1884 to 1888.
[1] Pisani emphasized in his works that pretended racial unity of the population of the Illyrian Provinces was partially imagingary.
