Ensayo sobre los alphabetos de las letras desconocidas, que se encuentran en las mas antiguas medallas, y monumentos de España
A 1752 Spanish numismatic treatise printed in Madrid by Antonio Sanz, written by the Marqués de Valdeflores to study unknown letters on ancient coins and monuments of Spain. Its engraved plates show rows of paired coin faces and reverses, with heads in profile, horses, animals and inscribed legends drawn in fine line on plain paper. A designer could take from them the crisp hatching, the circular medallion framing and the tidy grid layout of antique coin studies.
