The Persian poet Hafez wrote a form of poetry called the Ghazal. The Ghazal is a poetic form consisting of rhyming couplets and a refrain, with each line sharing the same meter. A Ghazal may be understood as a poetic expression of both the pain of loss or separation and the beauty of love in spite of that pain. In style and content it is a genre that has proved capable of an extraordinary variety of expression around its central themes of love and separation.

The Ghazal became very popular in Germany during the 19th century; the form was used extensively by Friedrich Rückert (1788–1866).

The following chapter of The Emerald Archive is about the poem “I Have Become Lost to the World”  — a poem written by Friedrich Rückert.
