Jim Leftwich

In 1997 visual poets Tim Gaze and Jim Leftwich first applied the word asemic to name their quasi-calligraphic writing gestures. They then began to distribute them to poetry magazines both online and in print. The authors explored sub-verbal and sub-letteral forms of writing, and textual asemia as a creative option and as an intentional practice. Since the late 1990s, asemic writing has blossomed into a worldwide literary/art movement. It has especially grown in the early part of the 21st century, though there is an acknowledgement of a long and complex history which precedes the activities of the current asemic movement, especially with regards to abstract calligraphy, wordless writing, and verbal writing damaged beyond the point of legibility.
