Calligraphy (from Greek: καλός, beautiful and γράφειν, writing) is the art of calligraphy. Chinese calligraphy is still highly regarded in China and Japan, and Islamic cultures have numerous calligraphy versions of the Qur'an, and calligraphy texts from the Qur'an are often incorporated into tapestries or hung on the wall. In Europe, calligraphy was initially performed by slaves (Roman Empire), later after the breakthrough of Christianity by monks in monasteries. In the later Middle Ages, guilds arose for calligraphers and illuminators (they made decorations for the letterwork). Different styles of calligraphy can be distinguished, including Gothic, Romanesque, Carolian and Beneventan. Chinese calligraphy has been included in UNESCO's list of Masterpieces of the Oral and Intangible Heritage of Humanity since 2009.
