Tortelli is said to have served as librarian to Pope Nicholas V, the great humanist patron whose collection formed the basis of the Vatican Library. "Discussing the question of the supposed Greek derivation of Latin words in the Orthographia, Tortelli refers to such new inventions and delights as the mechanical clock, the compass, and sugar as examples of words not derived from Greek" (Keio University Libraries Special Collections).
