Final answer:
Hakim-a-Barber is a reference to a satirical story in the Khamsah of Nizami, where the barber's presumptuous request to marry Harun al-Rashid's daughter reveals a hidden treasure beneath his feet.
Step-by-step explanation:
The significant aspect of the name Hakim-a-Barber in reference to Walker's satire lies in the story from the Makhzan al-Asrar, where Harun al-Rashid, a caliph, is approached impertinently by his barber for his daughter's hand in marriage while at a hammam. This incident occurs in the illustrated parable from the Khamsah of Nizami, depicted in a folio attributed to Bihzad and Mirak. The narrative bridges the themes of the power dynamics, depicting the inversion of social roles in the confined space of the bathhouse and the revelation of hidden treasure beneath the barber's feet after the caliph commands him to move from his usual place.
The folio is a visual representation of the story's key moment, where the barber's audacity is highlighted. The rich architectural depiction within the artwork and the narrative draw the viewer's eye across the scene, mirroring the Persian script's reading direction.
