Buffon, Georges Louis Leclerc, Comte de (1707–88) Buffon was an extremely influential French natural philosopher whose extensive works included one of the last speculative cosmogonies: Les Époques de la Nature (1778). Beginning with the formation of the Earth, it covered seven epochs in analogy to the seven days of Creation. He proposed that the Earth was hot at its creation and, from the rate of cooling, calculated its age to be more than 100 000 years.
