Jean Jacques Barthélemy was a French abbé who in his multivolume work, Voyage de jeune Anacharsis en Grèce dans le milieu du quatriéme siècle avant l'ère vulgaire (1788), reminds his readers of the important contributions to the extraterrestrial life debate made by Democritus, Leucippus, Petron, Pythagoras and his followers, Xenophanes, and others, two thousand years earlier.
