The word calligraphy means "beautiful writing." Arabic calligraphy has beautiful lines and shapes. But the true beauty of calligraphy is that it is used to write the holy words of the Qur'an, That is how and why the art of Arabic calligraphy started. The first Arabic system of writing (script) was very simple. Then, with the spread of Islam, there was a need for a more expressive form of writing to communicate Allah's words in the Holy Qur'an. It was important to have a clear script that all the people of Islam could easily read and understand.
