Henri Matisse's art in the early 1900s marks a period of vibrant experimentation and innovation that established him as a leading figure in modern art. During this time, Matisse became a central figure in the Fauvist movement, characterized by its bold use of color and disregard for classical or realistic representations. The intense colorism of his works from 1900 to 1905, such as "Woman with a Hat" (1905), brought him notoriety as one of the Fauves, or "wild beasts," a term coined by critics shocked by the unconventional hues of his palette​ (Encyclopedia Britannica)​​ (Wikipedia)​. One of Matisse's most notable works from this period, "Blue Nude (Souvenir de Biskra)" (1907), showcases his bold approach to color and form. This painting, a response to traditional nudes depicted in the Paris Salon, presents the figure in a hard and angular manner, a tribute to both Cézanne and the sculptures Matisse observed in Algeria. This work underscores Matisse's departure from conventional beauty, opting instead for a representation that emphasizes form and color over realism​ (The Art Story)​. Another significant piece, "The Back I" (1908-09), is part of a series of relief sculptures that demonstrate Matisse's exploration of the relationship between the figure and background, further highlighting his innovative approach to form. This series was inspired by his admiration for Auguste Rodin and represents a progressive simplification and abstraction of the human figure​ (The Art Story)​. "The Moroccans" (1915-16) and "Bathers by a River" (1917) reflect Matisse's continued evolution and experimentation with form, color, and composition. These works incorporate elements of Cubism and are noted for their abstract motifs and diagrammatic composition, diverging from Matisse's earlier Fauvist style. "The Dance II" (1932), commissioned by Albert Barnes, is another exemplary work from this period, showcasing Matisse's use of dynamic composition and vibrant color to depict movement and harmony​ (The Art Story)​. Throughout the 1900s, Matisse's art underwent significant transformations, moving from Fauvism towards a more abstract and simplified expression. This evolution was driven by his continuous search for an art of "balance, purity, and serenity," a quest that would define his contributions to modern art. Matisse's work from this era laid the groundwork for his later experiments with cut-outs and continued to influence the trajectory of 20th-century art​ (Encyclopedia Britannica)​​ (Wikipedia)​.
