The shahada

The art of producing calligraphic using dried leaves is one that was practiced mostly in Ottoman Turkey during the nineteenth century.  Viewed largely in an artisanal light, the production is nevetheless painstaking and the results charming. A leaf is placed between two sheets of glass and left to dry away from direct sunlight, a sharp implement is used to delicate prise away the body of the leaf from its skeleton leaving the required design. The art form was largely associated with the sufis, who saw in the deterioration of the leaf a metaphor for the transience of life and the eternity of the spiritual world.
