He graduated in Law in 1897 from the University of Bologna and entered the consular career, following a competition, in 1900. Marescotti was an associate of Prime Minister Sidney Sonnino and was appointed to the Paris Conference. He was Envoy Extraordinary and Minister Plenipotentiary in The Hague (February 1920), Sofia (1920 - 1923) and Cairo (March 1923).
