I had heard that in Germany and France, PhD students were required to have take classes in calculus and astronomy.
A basic knowledge in the lingua franca of the sciences would provide a proper perspective on the study of any ancient civilization. Otherwise everything becomes a representation of religious rituals.
A study of recent human history would also be helpful in the study of ancient civilizations. For example, many Egyptologists routinely deride the concept of a grand plan for Giza (e.g, building 3 pyramids to resemble Orion's Belt) as a violation of some ban on 'pan generational' design in the religion of the AE.
By that same logic, future historians would deny the existence of a Spanish Armada by saying that Catholic Spain would not violate the tenets of the Sermon on the Mount.
