A short time was spent in assisting a gentleman in Peru who was seeking to prove an Aryan affinity for the dialects spoken by the Quechua of that country to publish his research, but in 1868 Maspero was back in France at more profitable work. In 1869 he became a teacher ("répétiteur") of Egyptian language and archeology at the "École pratique des hautes études", and in 1874 he was appointed to the chair of Champollion at the "Collège de France", succeeding Emmanuel de Rougé.
