There were also by-laws, which provided that no master should accept a pupil for less than three years, and this acceptance had to be definitely registered by the public notary, a son, brother, grandson, or nephew being the only exceptions. No master might receive an apprentice who should have left another master before his time was out, unless with that master’s free consent. There were penalties for enticing away a pupil, and others to be enforced against pupils who broke the agreement. Severe restrictions existed with regard to the sale of pictures, no one but a member of the Guild being allowed to sell them. No one might bring a work from any foreign place for purposes of sale. It might not even be brought to the town without the special permission of the Gastaldiones, or trustees of the Guild, and those trustees were permitted to search for and destroy forged pictures. Every painter, therefore, had to subordinate his interests and inclinations to the local school. It helps us to understand why the individual character of the different masters is so perceptible, and one of the primary causes of this must have been the careful training of the pupils in the master’s workshop.
