All scholars admit that J.-J. Winckelmann is the father of Classical Archaeology, however few know the relevant contribution of Count de Caylus during the 18th century. His rich personality led him to take progressive for his time, reformative positions that laid the foundations for the modern approach of ancient Greek art. As regards the efforts of the two forementioned scholars for the scientifically documented dating of the history of Greek art. it would only be fair Winckelmann and Count de Caylus to be considered equal.
