A few specimen of wood block printing, possibly called "tarsh" in Arabic, have been excavated from a 10th-century context in Arabic Egypt. They were mostly used for prayers and amulets. The technique may have spread from China or been an independent invention, but had very little impact and virtually disappeared at the end of the 14th century. In India the main importance of the technique has always been as a method of printing textiles, which has been a large industry since at least the 10th century.
