Vitruvius

“The ideal architect should be a man of letters, a skillful draftsman, a mathematician, familiar with historical studies, a diligent student of philosophy, acquainted with music, not ignorant of medicine, learned in the responses of jurisconsults, familiar with astronomy and astronomical calculations.”
― Vitruvius

“If nature has composed the human body so that in its proportions the seperate individual elements answer to the total form, then the Ancients seem to have had reason to decide that bringing their creations to full completion likewise required a correspondence bewteen the measure of individual elements and the appearance of the work as a whole.”
