The transcoding of the alphabet, its binary encoding in accordance with the flag alphabet, the semaphore, and appear on four tapestries woven by the zero-one (under-over) Jacquard process. The Jacquard loom was invented in the 18th century to enable the production of complex weaving patterns instructed by punched cards. Based on the principle that weaving is a code, these four pieces incorporate some of the abovementioned configurations. The fabric becomes a language pattern that extends the notion of the flag as a signal to the tapestry as an encyclopaedia. The many possible ways of structuring the combinations produce diverse geometrical patterns, thus creating another connection between formal logic and written language.
