A collection of poems, usually by a single author, or a high-ranking official council in Muslim governments.
From Persian dīwān and Arabic dīwān, originally meaning a book of accounts or register. The sense evolved to mean a collection of poems and an administrative body.
The most famous diwan is probably that of the Persian poet Hafiz (14th century), whose mystical poetry became so beloved that Sufi devotees practiced 'bibliomancy' by randomly opening his diwan for spiritual guidance.
