Littré's translation of the writings attributed to Hippocrates of Cos, "The Father of Medicine"
Writings attributed to Hippocrates, about sixty in number, written in the Ionian dialect of Greek, have survived to the present, in Greek, with French translations, residing in a 19th century ten-volume work by the French scholar, Émile Littré, completed in 1862.  Littré ((Maximilien-)Paul-Émile Littre) received education in medicine and in numerous languages, including Greek, Latin, German, English and Sanskrit, and, as discussed above, gained repute for his lexicographic work, a scholarly dictionary of the French language, considered “….one of the outstanding lexicographic accomplishments of all time.” Jouanna states that "....
