Portrait of Italo Mariotti, classical philologist and in particular Latinist; a professor at the Universities of Urbino, Freiburg and Bologna. The analysis focuses on his philological method and unconventional topics of research, and in particular on translations from Latin and Greek. The Appendices contain a bibliography of Mariotti’s writings and an Errata corrige to his 1995 edition of the fragments of Lucilius, which the author had annotated in a copy now in the Raimondi Library of the University of Bologna.
