Zoomorphic Calligraphy

'Zoomorphic Calligraphy established itself only relatively late in Islamic art, when the taboos outlawing religious iconography had lost some of their power. It is an art developed in Ottoman Turkey, India and Qajar Iran. People say, it was known as early as 1458. Most of the below zoomorphic and anthropomorphic optical illusions were done by talented artist, named Hassan Musa from Sudan.'
