Art history is concerned with all the creative visual objects that have come into being over the past 2,000 years. The history of art thus intersects with art history as a discipline: artistic creations intersect with the canonization and academization processes inherent to a subject in the Humanities. The starting point of the discipline is the conviction that the images, the formal solutions, the prime examples of artistic mastery or expressiveness are, from the very outset, dependent on the mentalities and conceptualizations, the expectations and forms of access to the world that are given and possible in a specific historical situation. From out of this complex set of possibilities a style is stylized, and the clusters of stylizations are known as eras. A review of these eras stretches from antiquity to the present day.
