 According to this theory, S-shaped curved lines signify liveliness and activity and excite the attention of the viewer as contrasted with straight lines, parallel lines, or right-angled intersecting lines, which signify stasis, death, or inanimate objects.In contrast to grand compositional lines, which are regularly found in Baroque or Rococo art, the serpentine line is not primarily dictating the whole composition of a canvas.Instead, the line should be understood as being found in parts; a composition is created by employing various kinds of lines in various relations to each other without destroying its simplicity.
