Citaat van Alberti - Fenna

"I will make use of an Example to illustrate my Meaning. Some admire a Woman for being extremely slender and fine shaped; the young Gentleman in "Terence" prefered a Girl that was plump and fleshy: You perhaps are for a Medium between these two Extremes, and would neither have her so thin as to seem wasted with Sickness, nor so strong and robust as if she were a Ploughman in Disguise, and were fit for Boxing: In short, you would have her such a Beauty as might be formed by taking from the first what the second might spare." (Van: http://www.aboutscotland.co.uk/harmony/harmony.html) In dit stuk tekst wordt voor mij goed duidelijk waarom deze architecten met verhoudingen en proporties werkten om perfectie na te streven.
