Described as a mini-Taj, this is the tomb of Mirza Ghiyath Beg, who served under Akbar and fathered Nur Jahan, the powerful wife of Jahangir who helped promote her father to his position as Lord of the Treasury and enshrined him here in this "bejeweled marble box" -- proof of her powerful hold on the purse strings. Also built of translucent white marble, it was the most innovative building of 17th-century India, and marked the transition from the heavy red sandstone so favored by previous Mughal emperors. It no doubt inspired Shah Jahan with its beautiful symmetry and detailing; the pietra duras are as delicate as embroidery, and the dense gilding and paintwork feature typical Persian motifs, such as the wine-vase and the dish and cup, much favored by Jahangir at the time. The scale may be far less grand than that of the Taj, but the polychrome geometric ornamentation is more obviously decorative, and given the beauty of the proportions and the intricacy of its inlays and mosaics, it's amazing how little traffic this tomb sees relative to the Taj. It definitely warrants a short visit, if only to get a sense of how almost generic opulence was to the Mughal court.
