title: [Expertise and construction of artistic value (14(th) to 15 (th) centuries)].
abstract: Working from a body of Tuscan commission contracts from the 14(th) and 15(th) centuries, this article shows how painting was the object of concrete evaluative practices among professional painters before becoming the subject of discussion for scholars and humanists. This study rests on the legal and economic analysis of clauses of expertise by which painters and commissioners submitted the work to other painters in order to guarantee the proper execution of the contract, thus constituting an essential evaluative measure for the economy of painting.
