The Mannerist movement arose in the late period of the High Renaissance in art. It appeared in Italy and lasted between 1520. and 1580. It was often called the "anti-classical" movement, and it stood out for its idealization of themes, staged and exaggerated depictions. In an artistic context, the term mannerism originates from Vasari, and it was in common use much earlier in literary and social contexts. Vasari uses "manner" as an equivalent for "style". The characteristics of Mannerism require poise, refinement, sophistication, refinement, and works of art that are selective and idealized. Prominent painters who worked in the Mannerism period and who are presented to preschool children through art activities in this work are Hieronymus Bosch, Jacopo de Pontormo, Sofonisba Anguissola and Giuseppe Arcimboldo. Hieronymus Bosch is known for works in which "horror vacui" or "fear of empty space" prevailed. In his paintings, Jacopo de Pontormo made a transition from the classic, common expression of Mannerism to a new style of Mannerism sensibility. Sofonisba Anguissola was the greatest woman who created during the Mannerism period and was atypical in her rise to fame because she did not come from a family of artists, and women were then forbidden to become apprentices to master artists in such cases. She was known for portrait and self-portrait paintings. Giuseppe Arcimboldo was adored among his contemporaries and had a wonderful approach to portrait painting, he approached it allegorically. He is best known for his two works of paintings "Four Seasons" and "Four Elements" in which he allegorically depicted the sovereigns of the Imperial Habsburg court. The preschool children were introduced to the Mannerism movement and its characteristics, observed works of art by the aforementioned artists, and were inspired to express themselves artistically.
