Neoclassicism was an art movement that used and revolved around the concept of Greek and Roman style and classical themes. The movement came about a period after Romanticism, during the late 1700's through early 1800's, but is commonly referred to today as being part of the 19th century. Neoclassicism is characterized by strict rules of decorum, harmony, proportion and taste; thus bringing back an appreciation for classical versions of these traits. The style diverged from Romanticism due to its focus on symmetry and restraint rather than emotional expression. Neoclassicism focuses on the human form and strives to emulate classical Greek styles. Artists drew inspiration from antiquity and focused on ancient Greco-Roman culture for a variety of reasons; including their accomplishments in art, architecture, literature and philosophy. Neoclassicism was not originally a movement, but rather a revival of classical art and architecture; especially the styles that were prominent in ancient Greek culture.
