Bowl with Kufic Inscription, 10th century, Samanid Period. Earthenware. Greater Khurasan/Northeastern Iran. Via Brooklyn Museum.
The inscriptions on these types of vessels are the first examples of Arabic proverbs to appear in the Islamic world, and thus are central to Arabic literary history. This one reads, “Peace is that which is silent and the inner [thoughts] of the man with faults will only be revealed through his speech.”
