The text provides a series of anecdotes to describe the four advisers every Islamic prince required: a scribe, a poet, an astrologer, and a physician. This scene recounts the story of the Abbasid caliph (Islamic leader) al-Mamun (786-883 CE), depicted here in his resplendent palace as he falls in love with and quickly proposes marriage to his advisers daughter. Quoting the Quran, she demands his patience. Impressed by her firm literary grounding, al-Mamun willingly obliges.
