The striped textiles of Yemen were famous throughout the Islamic world. They were made in the resist‑dyed ikat technique to form patterns of arrowheads and diamonds. Inscriptions on Yemeni ikats are often painted, as in this example. Such inscribed textiles were called tiraz, from the Persian word meaning "embroidery." They were produced in tiraz workshops under royal control. Such textiles usually bore inscriptions naming the current ruler or caliph to whom the recipient owed loyalty. Tiraz textiles were presented by rulers as robes of honor at formal ceremonies.
