This is a battle which has gone on for a long time.
I have out from the library "The Sistine Chapel- A glorious restoration" various authors published in conjunction with Japanese TV (NTV)1994. It is a book detailing the fresco and construction techniques.

You know that originally Michelangelo, mainly known as a sculptor, had a battle getting his work done in buon fresco. His adversary was Sebastiano, who wanted oil. Michelangelo is reported to say "oil painting is a woman's art and only fit for the lazy and well-to-do people like Fra Sebastiano"

And for the record, I am more widely known as a sculptor/moldmaker than as a ornamental plasterer. Most of my work is commercial in nature, I build, and often improve, things which other people design.
