The correct option is Portraiture.
Explanation
The Mughal School of painting was characterized by a highly organized atelier system (karkhanas) where specific terms were used to denote different genres, techniques, and stages of painting. The terminology often has Persian roots.
Analysis:
- Landscape painting is incorrect: While landscapes were intricately detailed in Mughal miniatures, often showing Persian influence with high horizons and rocky formations, the term chiharanama does not refer to them.
- Portraiture is correct: The term Chiharanama is derived from the word Chihara, which means "face." It specifically refers to portraiture. The Mughal emperors, particularly Akbar and Jahangir, laid great emphasis on realistic portraits. Akbar commissioned portraits of himself and his nobles to be collected in an album, establishing portraiture as a distinct and significant genre within the school.
- Calligraphy is incorrect: Calligraphy was considered a superior art form in the Islamic world and the Mughal court, but it is known as Khushnavisi or Khattati.
- Book binding is incorrect: Book binding was a separate craft essential for the creation of manuscripts and albums (Muraqqas), but it is not associated with the term chiharanama.
Key Takeaway: Chiharanama refers to the art of portraiture in Mughal painting, a genre that moved away from the idealized forms of earlier Indian art toward realistic representation of the subject's face and personality.
