Studies composed by Domenico Ercole Del Rio (Italy, 1718-1802).
Some suggest his year of birth is 1723 or 1726?
His signature.
Del Rio was a lawyer by profession.
Because he published his first book, Sopra il Giuoco degli Scacchi Osservazione Pratiche d'Anonimo Autore Modenese,
anonymously as the title suggests, he has been referred to as the Anonymous Modenese.
His book was 110 pages and later expanded by his compatriot, Lolli.
Del Rio's other book, La Guerra degli Scacchi (The War of the Chessman) was only published in translation in 1984 by Christopher Becker.
