Antonio Manciolino - On "Professionalism"
"the art is not a harlot to suffer itself to be sold. And I wish to hold to a more useful path, noting that the school should be devoted to offering some instruction of the art. It is of more worth to me to be useful to my scholars with this work than, through the putting of a price to the play, to provide myself alone with great benefit." - Antonio Manciolino, Bolognese 1531
