Origin of the contemporary art market
So far we have said that the origins of the market are very ancient, but in truth to speak of a free market , the one based on the system of private galleries, which corresponds to the current structure of the contemporary art market, we have to go back to the 19th century.
It is therefore necessary to take a step back and examine the circumstances of its birth and development, which were built on the foundations of a new and radical transformation and revolution in the conceptions of art at the end of the 19th century.
We are therefore referring again to the mid-seventeenth century, a period that saw the birth of a monopoly even more restrictive and rigidly structured, if you will, than the previous ones: that of the art academies . Founded with the aim of officially legitimizing the validity of artistic production, these institutions effectively controlled it until the second half of the nineteenth century.
Let's examine the French model in particular. 1648 was the year in which the Académie Royale de Peinture et Sculpture was founded in Paris, the most influential body of institutional recognition. It organized annual exhibitions, the Salons , whose participation or exclusion determined the artists' entire careers, their chances of affirmation, and their commercial success. The judging panel consisted of academics, teachers from the Ecole des Beaux-Arts, and the director of the French Academy in Rome (the capital of ancient and classical art). Acceptance of works by this panel depended on their conformity to classical aesthetic theory, which the institution aimed to defend and preserve. Artists aligned with academic canons received prizes at the Salons and commissions to create public works, and their works were proposed to public institutions and museums for purchase. If we also keep in mind that the Academy's statute forbade official artists from directly marketing their own works, we realize the total control it exercised both over the content of the works and over their marketing.
The market, therefore, which had incredibly developed in the 16th and 17th centuries, as mentioned earlier, was not a free market, but rather heavily constrained by these institutions, which, moreover, combined with the conformist approach of criticism and the dominant taste of the upper-middle-class public, left no room for the emergence of innovative artistic production. An officially regulated, regulated, and limited artistic production was inextricably linked to an equally regulated and consequently limited official market.
This situation began to change in the second half of the nineteenth century , with the emergence of Romantic ideals over Classicist ones. And it was precisely France that was at the forefront of this transformation, which saw the birth and development of independent exhibitions organized by the artists themselves, on the one hand, and a new type of private gallery, on the other. Starting with exhibitions, let's briefly recall that 1855 was the year of the Universal Exhibition in Paris, which included works by artists from twenty-eight countries, as well as paintings rejected by the Salon jury. Meanwhile, 1863 saw the Salon des Réfusés, the first (and only) exhibition entirely dedicated to artists excluded from the official Salon.
It should be kept in mind that among the innovative artists of the latest generation, mistreated and excluded from the official circuits, there were names like Cézanne (who tried every year to send his works to the Salon without ever being accepted!) and like the Impressionists, who were among the first to demand and pursue their independence from the academic supremacy, and thus constituted themselves as a revolutionary reaction movement to the dominant situation (just think that the term "impression" was used for the first time in 1874 [1] with an ironic and negative meaning to describe their works).
After these first initiatives, more or less successful, a true alternative salon was born in 1884: the Salon des Artistes Indépendants, organized by the Société des Artistes Indépendants, which provided for neither prizes nor a jury.
The Salon d'Atomne, founded in 1903, was this time equipped with a jury, with the specific aim of shaping the tastes of the public and collectors by directing them toward innovative trends in contemporary art. This particularly successful event hosted exhibitions of historic importance, such as those of the Fauves and Cubists, as well as a Cézanne retrospective.
But let us return to the Impressionists , to underline how crucial their movement is, because it inaugurates the creation of an avant-garde art , that is, of modernism , an aesthetic revolution in pictorial language, but also the creation of an alternative market , made up of private galleries, which through new commercial and promotional strategies, had to invent a new market that corresponded to the new art. The partnership with Paul Durand Ruel (1870), marks the appearance of the first truly modern dealer, an innovator both in terms of artistic choices and in terms of commercial and critical strategies. Ruel's new commercial system, which would later become the model of the new international avant-garde market, consists of:
