In 1902 he made his first trip to Venice, a place he fell in love with and would return to almost every year until 1939, except during World War I.

Art critic Marius-Ary Leblond wrote that his Venice works "follow in the great tradition of the Venetian Masters, he puts himself in the direct line of succession to the Italians; he remains an opulent and aristocratic Venetian in his works."

Bernheim-Jeune (an important Paris art dealer) bought his "Rue à l'omnibus" at the Salon des Indépendants.

Folco was a well known "manadier" who raised bulls for bullfights on his estate in Camargue and befriended Buffalo Bill.

Along with Marguerite, who was queen of the Félibrige from 1906 to 1913, Folco was a friend of provençal poets Mistral and Joseph d'Arbaud.
