Serpentine lines from Hogarth's The Analysis of Beauty. Line of beauty is a term and a theory in art or aesthetics used to describe an S-shaped curved line (a serpentine line) appearing within an object, as the boundary line of an object, or as a virtual boundary line formed by the composition of several objects.
Line art or line drawing is any image that consists of distinct straight lines or curved lines placed against a background (usually plain). Two-dimensional or three-dimensional objects are often represented through shade (darkness) or hue . Line art can use lines of different colors, although line art is usually monochromatic.
Twisting and curving line forms have a long history in art and design. Whiplash curves have similarities with the arabesque design, used particularly in Islamic art, such as the ceramic tiles of the mosque of Samarkand in Central Asia. Curvilinear design is a noticeable element of Gothic architecture, in, for example, church window tracery.
Positive space refers to the areas of the work with a subject, while negative space is the space without a subject. [6] Open and closed space coincides with three-dimensional art, like sculptures, where open spaces are empty, and closed spaces contain physical sculptural elements. [6]
Although space-filling curves have a long history in China in motifs more than 2,000 years earlier, extending back to Zhukaigou Culture (c. 2000 BC – c. 1400 BC) and Xiajiadian Culture (c. 2200 BC – c. 1600 BC and c. 1000 BC – c. 600 BC), frequently there is speculation that meanders of Greek origin may have come to China during the time ...

The Vertical-horizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length. Vista paradox: Visual tilt effects: Wagon-wheel effect: White's illusion: Wundt illusion: The two red vertical lines are both straight, but they may look as if they are bowed inwards to ...
