A 400 years old an Arabic inscription is written in decorative, linear Kufic script. Written by one of 9 saints of indonesia (wali Songo) The script is more important as a decorative element than for the message it carries. The inscriptions on most such bowls are proverbs, good wishes, or maxims rather than religious sayings or verses from the Koran. The Saints conveyed the divine message in Arabic, and so the language and script themselves acquired a sacred character. For this reason, calligraphy became one of the most exalted art forms in the Islamic world. And adapted into wayang stories.
