Kit out a camera with the world’s best mechanical optics, AI and those slick salesmanship megapixel baits. It gives you a photo—a beautiful picture in digital high definition that guarantees instant Instagram likes. But no camera has been invented yet that can capture the mood—the mahaul as Bahadur Shah Zafar’s court poet Zauq would say about the burst of emotions when he serenaded his muse with his quill pen on scented, handmade paper; the moon smiling coyly on the chhajja. And Zauq’s guiding light? His beloved Dilli, its mohallas, its people, its storied architecture…the Qutub Minar, that shady nook under a tree on the sprawling garden encircling the tomb of Safdarjung, the red sandstone mausoleum under whose central onion dome rests emperor Humayun. On moonlit nights, the splendour of Humayun’s tomb approaches the ethereal glow of the Taj—reflecting the inspirational template for Shahjahan’s white marble cenotaph for his favourite queen.
