Arabic block printing may have its origins in China, and interactions through trade and expansion would have set the stage for the transmission of such printing knowledge in the early Islamic period (7th to 9th centuries). Produced between the 9th and the 14th centuries, medieval Arabic block printing was done with wooden blocks, though some was also produced using metal blocks. Arabic block-printed materials include royal decrees from 10th-century al-Andalus, paper currency from 12th-century northern Syria, and amulets like the one presented here.
