The only time we have written records is when the architect wasn’t actually there.
Perhaps the architect was away on business and had to write out instructions and send them to the shop.
And another thing to think about: what effect do you suppose this approach would have had on innovation?
I mean, since the hired artisans had been trained by other artisans, they tended to be trained to use traditional styles and techniques.
So if you’re a master architect, uh, you’ve developed your own style.
Say you’re calling for certain detail in the building you’re designing, right?
And say this detail is different, purposely different, from the established tradition, the established style.
Well, most likely when the hired artisans would execute the design, rather than follow the intended design, they would stick with the more traditional style that they were familiar with.
Workers would have to be supervised very closely to prevent this from happening.
Otherwise, as it often happened, there goes the designer’s style and creativity.
