El <i>Vocabulario en seis lenguas</i> (1626) de Miguel Agustín: ¿un fraude?

This article offers a comprehensive description of Miguel Agustín’s Vocabulario en seis lenguas (1626), one of the first lexicographical works in the field of geoponics and one of the additions to the author’s own Spanish translation of his Llibre dels secrets de agricultura, casa rústica y pastoril (1617). Particular attention is paid to its structure, the presumed lexicographical criteria that guided its development, the sources followed, and the equivalences offered for Spanish, Catalan, Latin, Portuguese, Italian, and French, respectively. Finally, its degree of originality is assessed.
